![bignumber.js](https://raw.githubusercontent.com/MikeMcl/bignumber.js/gh-pages/bignumberjs.png)
A JavaScript library for arbitrary-precision decimal and non-decimal arithmetic.
[![Build Status](https://travis-ci.org/MikeMcl/bignumber.js.svg)](https://travis-ci.org/MikeMcl/bignumber.js)
<br />
## Features
- Integers and decimals
- Simple API but full-featured
- Faster, smaller, and perhaps easier to use than JavaScript versions of Java's BigDecimal
- 8 KB minified and gzipped
- Replicates the `toExponential`, `toFixed`, `toPrecision` and `toString` methods of JavaScript's Number type
- Includes a `toFraction` and a correctly-rounded `squareRoot` method
- Supports cryptographically-secure pseudo-random number generation
- No dependencies
- Wide platform compatibility: uses JavaScript 1.5 (ECMAScript 3) features only
- Comprehensive [documentation](http://mikemcl.github.io/bignumber.js/) and test set
![API](https://raw.githubusercontent.com/MikeMcl/bignumber.js/gh-pages/API.png)
If a smaller and simpler library is required see [big.js](https://github.com/MikeMcl/big.js/).
It's less than half the size but only works with decimal numbers and only has half the methods.
It also does not allow `NaN` or `Infinity`, or have the configuration options of this library.
See also [decimal.js](https://github.com/MikeMcl/decimal.js/), which among other things adds support for non-integer powers, and performs all operations to a specified number of significant digits.
## Load
The library is the single JavaScript file *bignumber.js* (or minified, *bignumber.min.js*).
Browser:
```html
<script src='path/to/bignumber.js'></script>
```
[Node.js](http://nodejs.org):
```bash
$ npm install bignumber.js
```
```javascript
const BigNumber = require('bignumber.js');
```
ES6 module:
```javascript
import BigNumber from "./bignumber.mjs"
```
AMD loader libraries such as [requireJS](http://requirejs.org/):
```javascript
require(['bignumber'], function(BigNumber) {
// Use BigNumber here in local scope. No global BigNumber.
});
```
## Use
The library exports a single constructor function, [`BigNumber`](http://mikemcl.github.io/bignumber.js/#bignumber), which accepts a value of type Number, String or BigNumber,
```javascript
let x = new BigNumber(123.4567);
let y = BigNumber('123456.7e-3');
let z = new BigNumber(x);
x.isEqualTo(y) && y.isEqualTo(z) && x.isEqualTo(z); // true
```
To get the string value of a BigNumber use [`toString()`](http://mikemcl.github.io/bignumber.js/#toS) or [`toFixed()`](http://mikemcl.github.io/bignumber.js/#toFix). Using `toFixed()` prevents exponential notation being returned, no matter how large or small the value.
```javascript
let x = new BigNumber('1111222233334444555566');
x.toString(); // "1.111222233334444555566e+21"
x.toFixed(); // "1111222233334444555566"
```
If the limited precision of Number values is not well understood, it is recommended to create BigNumbers from String values rather than Number values to avoid a potential loss of precision.
*In all further examples below, `let`, semicolons and `toString` calls are not shown. If a commented-out value is in quotes it means `toString` has been called on the preceding expression.*
```javascript
// Precision loss from using numeric literals with more than 15 significant digits.
new BigNumber(1.0000000000000001) // '1'
new BigNumber(88259496234518.57) // '88259496234518.56'
new BigNumber(99999999999999999999) // '100000000000000000000'
// Precision loss from using numeric literals outside the range of Number values.
new BigNumber(2e+308) // 'Infinity'
new BigNumber(1e-324) // '0'
// Precision loss from the unexpected result of arithmetic with Number values.
new BigNumber(0.7 + 0.1) // '0.7999999999999999'
```
When creating a BigNumber from a Number, note that a BigNumber is created from a Number's decimal `toString()` value not from its underlying binary value. If the latter is required, then pass the Number's `toString(2)` value and specify base 2.
```javascript
new BigNumber(Number.MAX_VALUE.toString(2), 2)
```
BigNumbers can be created from values in bases from 2 to 36. See [`ALPHABET`](http://mikemcl.github.io/bignumber.js/#alphabet) to extend this range.
```javascript
a = new BigNumber(1011, 2) // "11"
b = new BigNumber('zz.9', 36) // "1295.25"
c = a.plus(b) // "1306.25"
```
Performance is better if base 10 is NOT specified for decimal values. Only specify base 10 when it is desired that the number of decimal places of the input value be limited to the current [`DECIMAL_PLACES`](http://mikemcl.github.io/bignumber.js/#decimal-places) setting.
A BigNumber is immutable in the sense that it is not changed by its methods.
```javascript
0.3 - 0.1 // 0.19999999999999998
x = new BigNumber(0.3)
x.minus(0.1) // "0.2"
x // "0.3"
```
The methods that return a BigNumber can be chained.
```javascript
x.dividedBy(y).plus(z).times(9)
x.times('1.23456780123456789e+9').plus(9876.5432321).dividedBy('4444562598.111772').integerValue()
```
Some of the longer method names have a shorter alias.
```javascript
x.squareRoot().dividedBy(y).exponentiatedBy(3).isEqualTo(x.sqrt().div(y).pow(3)) // true
x.modulo(y).multipliedBy(z).eq(x.mod(y).times(z)) // true
```
As with JavaScript's Number type, there are [`toExponential`](http://mikemcl.github.io/bignumber.js/#toE), [`toFixed`](http://mikemcl.github.io/bignumber.js/#toFix) and [`toPrecision`](http://mikemcl.github.io/bignumber.js/#toP) methods.
```javascript
x = new BigNumber(255.5)
x.toExponential(5) // "2.55500e+2"
x.toFixed(5) // "255.50000"
x.toPrecision(5) // "255.50"
x.toNumber() // 255.5
```
A base can be specified for [`toString`](http://mikemcl.github.io/bignumber.js/#toS). Performance is better if base 10 is NOT specified, i.e. use `toString()` not `toString(10)`. Only specify base 10 when it is desired that the number of decimal places be limited to the current [`DECIMAL_PLACES`](http://mikemcl.github.io/bignumber.js/#decimal-places) setting.
```javascript
x.toString(16) // "ff.8"
```
There is a [`toFormat`](http://mikemcl.github.io/bignumber.js/#toFor) method which may be useful for internationalisation.
```javascript
y = new BigNumber('1234567.898765')
y.toFormat(2) // "1,234,567.90"
```
The maximum number of decimal places of the result of an operation involving division (i.e. a division, square root, base conversion or negative power operation) is set using the `set` or `config` method of the `BigNumber` constructor.
The other arithmetic operations always give the exact result.
```javascript
BigNumber.set({ DECIMAL_PLACES: 10, ROUNDING_MODE: 4 })
x = new BigNumber(2)
y = new BigNumber(3)
z = x.dividedBy(y) // "0.6666666667"
z.squareRoot() // "0.8164965809"
z.exponentiatedBy(-3) // "3.3749999995"
z.toString(2) // "0.1010101011"
z.multipliedBy(z) // "0.44444444448888888889"
z.multipliedBy(z).decimalPlaces(10) // "0.4444444445"
```
There is a [`toFraction`](http://mikemcl.github.io/bignumber.js/#toFr) method with an optional *maximum denominator* argument
```javascript
y = new BigNumber(355)
pi = y.dividedBy(113) // "3.1415929204"
pi.toFraction() // [ "7853982301", "2500000000" ]
pi.toFraction(1000) // [ "355", "113" ]
```
and [`isNaN`](http://mikemcl.github.io/bignumber.js/#isNaN) and [`isFinite`](http://mikemcl.github.io/bignumber.js/#isF) methods, as `NaN` and `Infinity` are valid `BigNumber` values.
```javascript
x = new BigNumber(NaN) // "NaN"
y = new BigNumber(Infinity) // "Infinity"
x.isNaN() && !y.isNaN() && !x.isFinite() && !y.isFinite() // true
```
The value of a BigNumber is stored in a decimal floating point format in terms of a coefficient, exponent and sign.
```javascript
x = new BigNumber(-123.456);
x.c // [ 123, 45600000000000 ] coefficient (i.e. significand)
x.e // 2 exponent
x.s // -1 sign
```
For advanced usage, multiple BigNumber constructors can be created, each with their own independent configuration.
```javascript
// Set DECIMAL_PLACES for the original BigNumber constructor
BigNumber.set({ DECIMAL_PLACES: 10 })
// Create another BigNumber constructor, optionally passing in a configuration object
BN = BigNumber.clone({ DECIMAL_PLACES: 5 })
x = new BigNumber(1)
y = new BN(1)
x.div(3) // '0.3333333333'
y.div(3) // '0.33333'
```
For further information see the [API](http://mikemcl.github.io/bignumber.js/) reference in the *doc* directory.
## Test
The *test/modules* directory contains the test scripts for each method.
The tests can be run with Node.js or a browser. For Node.js use
$ npm test
or
$ node test/test
To test a single method, use, for example
$ node test/methods/toFraction
For the browser, open *test/test.html*.
## Build
For Node, if [uglify-js](https://github.com/mishoo/UglifyJS2) is installed
npm install uglify-js -g
then
npm run build
will create *bignumber.min.js*.
A source map will also be created in the root directory.

* Add `fields` argument to `query()` as well as `'fields'` event. This is
similar to what was available in 0.9.x.
* Support connecting to the sphinx searchd daemon as well as MariaDB (#199).
* Implement long stack trace support, will be removed / disabled if the node
core ever supports it natively.
* Implement `nestTables` option for queries, allows fetching JOIN result sets
with overlapping column names.
* Fix ? placeholder mechanism for values containing '?' characters (#205).
* Detect when `connect()` is called more than once on a connection and provide
the user with a good error message for it (#204).
* Switch to `UTF8_GENERAL_CI` (previously `UTF8_UNICODE_CI`) as the default
charset for all connections to avoid strange MySQL performance issues (#200),
and also make the charset user configurable.
* Fix BLOB type casting for `TINY_BLOB`, `MEDIUM_BLOB` and `LONG_BLOB`.
* Add support for sending and receiving large (> 16 MB) packets.
## v2.0.0-alpha (2012-05-15)
This release is a rewrite. You should carefully test your application after
upgrading to avoid problems. This release features many improvements, most
importantly:
* ~5x faster than v0.9.x for parsing query results
* Support for pause() / resume() (for streaming rows)
* Support for multiple statement queries
* Support for stored procedures
* Support for transactions
* Support for binary columns (as blobs)
* Consistent & well documented error handling
* A new Connection class that has well defined semantics (unlike the old Client class).
* Convenient escaping of objects / arrays that allows for simpler query construction
* A significantly simpler code base
* Many bug fixes & other small improvements (Closed 62 out of 66 GitHub issues)
Below are a few notes on the upgrade process itself:
The first thing you will run into is that the old `Client` class is gone and
has been replaced with a less ambitious `Connection` class. So instead of
`mysql.createClient()`, you now have to:
```js
var mysql = require('mysql');
var connection = mysql.createConnection({
host : 'localhost',
user : 'me',
password : 'secret',
});
connection.query('SELECT 1', function(err, rows) {
if (err) throw err;
console.log('Query result: ', rows);
});
connection.end();
```
The new `Connection` class does not try to handle re-connects, please study the
`Server disconnects` section in the new Readme.
Other than that, the interface has stayed very similar. Here are a few things
to check out so:
* BIGINT's are now cast into strings
* Binary data is now cast to buffers
* The `'row'` event on the `Query` object is now called `'result'` and will
also be emitted for queries that produce an OK/Error response.
* Error handling is consistently defined now, check the Readme
* Escaping has become more powerful which may break your code if you are
currently using objects to fill query placeholders.
* Connections can now be established explicitly again, so you may wish to do so
if you want to handle connection errors specifically.
That should be most of it, if you run into anything else, please send a patch
or open an issue to improve this document.
## v0.9.6 (2012-03-12)
* Escape array values so they produce sql arrays (Roger Castells, Colin Smith)
* docs: mention mysql transaction stop gap solution (Blake Miner)
* docs: Mention affectedRows in FAQ (Michael Baldwin)
## v0.9.5 (2011-11-26)
* Fix #142 Driver stalls upon reconnect attempt that's immediately closed
* Add travis build
* Switch to urun as a test runner
* Switch to utest for unit tests
* Remove fast-or-slow dependency for tests
* Split integration tests into individual files again
## v0.9.4 (2011-08-31)
* Expose package.json as `mysql.PACKAGE` (#104)
## v0.9.3 (2011-08-22)
* Set default `client.user` to root
* Fix #91: Client#format should not mutate params array
* Fix #94: TypeError in client.js
* Parse decimals as string (vadimg)
## v0.9.2 (2011-08-07)
* The underlaying socket connection is now managed implicitly rather than explicitly.
* Check the [upgrading guide][] for a full list of changes.
## v0.9.1 (2011-02-20)
* Fix issue #49 / `client.escape()` throwing exceptions on objects. (Nick Payne)
* Drop < v0.4.x compatibility. From now on you need node v0.4.x to use this module.

View file

@ -0,0 +1,136 @@
### Streams Working Group
The Node.js Streams is jointly governed by a Working Group
(WG)
that is responsible for high-level guidance of the project.
The WG has final authority over this project including:
* Technical direction
* Project governance and process (including this policy)
* Contribution policy
* GitHub repository hosting
* Conduct guidelines
* Maintaining the list of additional Collaborators
For the current list of WG members, see the project
[README.md](./README.md#current-project-team-members).
### Collaborators
The readable-stream GitHub repository is
maintained by the WG and additional Collaborators who are added by the
WG on an ongoing basis.
Individuals making significant and valuable contributions are made
Collaborators and given commit-access to the project. These
individuals are identified by the WG and their addition as
Collaborators is discussed during the WG meeting.
_Note:_ If you make a significant contribution and are not considered
for commit-access log an issue or contact a WG member directly and it
will be brought up in the next WG meeting.
Modifications of the contents of the readable-stream repository are
made on
a collaborative basis. Anybody with a GitHub account may propose a
modification via pull request and it will be considered by the project
Collaborators. All pull requests must be reviewed and accepted by a
Collaborator with sufficient expertise who is able to take full
responsibility for the change. In the case of pull requests proposed
by an existing Collaborator, an additional Collaborator is required
for sign-off. Consensus should be sought if additional Collaborators
participate and there is disagreement around a particular
modification. See _Consensus Seeking Process_ below for further detail
on the consensus model used for governance.
Collaborators may opt to elevate significant or controversial
modifications, or modifications that have not found consensus to the
WG for discussion by assigning the ***WG-agenda*** tag to a pull
request or issue. The WG should serve as the final arbiter where
required.
For the current list of Collaborators, see the project
[README.md](./README.md#members).
### WG Membership
WG seats are not time-limited. There is no fixed size of the WG.
However, the expected target is between 6 and 12, to ensure adequate
coverage of important areas of expertise, balanced with the ability to
make decisions efficiently.
There is no specific set of requirements or qualifications for WG
membership beyond these rules.
The WG may add additional members to the WG by unanimous consensus.
A WG member may be removed from the WG by voluntary resignation, or by
unanimous consensus of all other WG members.
Changes to WG membership should be posted in the agenda, and may be
suggested as any other agenda item (see "WG Meetings" below).
If an addition or removal is proposed during a meeting, and the full
WG is not in attendance to participate, then the addition or removal
is added to the agenda for the subsequent meeting. This is to ensure
that all members are given the opportunity to participate in all
membership decisions. If a WG member is unable to attend a meeting
where a planned membership decision is being made, then their consent
is assumed.
No more than 1/3 of the WG members may be affiliated with the same
employer. If removal or resignation of a WG member, or a change of
employment by a WG member, creates a situation where more than 1/3 of
the WG membership shares an employer, then the situation must be
immediately remedied by the resignation or removal of one or more WG
members affiliated with the over-represented employer(s).
### WG Meetings
The WG meets occasionally on a Google Hangout On Air. A designated moderator
approved by the WG runs the meeting. Each meeting should be
published to YouTube.
Items are added to the WG agenda that are considered contentious or
are modifications of governance, contribution policy, WG membership,
or release process.
The intention of the agenda is not to approve or review all patches;
that should happen continuously on GitHub and be handled by the larger
group of Collaborators.
Any community member or contributor can ask that something be added to
the next meeting's agenda by logging a GitHub Issue. Any Collaborator,
WG member or the moderator can add the item to the agenda by adding
the ***WG-agenda*** tag to the issue.
Prior to each WG meeting the moderator will share the Agenda with
members of the WG. WG members can add any items they like to the
agenda at the beginning of each meeting. The moderator and the WG
cannot veto or remove items.
The WG may invite persons or representatives from certain projects to
participate in a non-voting capacity.
The moderator is responsible for summarizing the discussion of each
agenda item and sends it as a pull request after the meeting.
### Consensus Seeking Process
The WG follows a
[Consensus
Seeking](http://en.wikipedia.org/wiki/Consensus-seeking_decision-making)
decision-making model.
When an agenda item has appeared to reach a consensus the moderator
will ask "Does anyone object?" as a final call for dissent from the
consensus.
If an agenda item cannot reach a consensus a WG member can call for
either a closing vote or a vote to table the issue to the next
meeting. The call for a vote must be seconded by a majority of the WG
or else the discussion will continue. Simple majority wins.
Note that changes to WG membership require a majority consensus. See
"WG Membership" above.

***Node-core streams for userland***
This package is a mirror of the Streams2 and Streams3 implementations in
Node-core.
Full documentation may be found on the [Node.js website](https://nodejs.org/dist/v8.11.1/docs/api/stream.html).
If you want to guarantee a stable streams base, regardless of what version of
Node you, or the users of your libraries are using, use **readable-stream** *only* and avoid the *"stream"* module in Node-core, for background see [this blogpost](http://r.va.gg/2014/06/why-i-dont-use-nodes-core-stream-module.html).
As of version 2.0.0 **readable-stream** uses semantic versioning.
# Streams Working Group
`readable-stream` is maintained by the Streams Working Group, which
oversees the development and maintenance of the Streams API within
Node.js. The responsibilities of the Streams Working Group include:
* Addressing stream issues on the Node.js issue tracker.
* Authoring and editing stream documentation within the Node.js project.
* Reviewing changes to stream subclasses within the Node.js project.
* Redirecting changes to streams from the Node.js project to this
project.
* Assisting in the implementation of stream providers within Node.js.
* Recommending versions of `readable-stream` to be included in Node.js.
* Messaging about the future of streams to give the community advance
notice of changes.

* **Google Hangouts Video**: http://www.youtube.com/watch?v=I9nDOSGfwZg
* **GitHub Issue**: https://github.com/iojs/readable-stream/issues/106
* **Original Minutes Google Doc**: https://docs.google.com/document/d/17aTgLnjMXIrfjgNaTUnHQO7m3xgzHR2VXBTmi03Qii4/
## Agenda
Extracted from https://github.com/iojs/readable-stream/labels/wg-agenda prior to meeting.
* adopt a charter [#105](https://github.com/iojs/readable-stream/issues/105)
* release and versioning strategy [#101](https://github.com/iojs/readable-stream/issues/101)
* simpler stream creation [#102](https://github.com/iojs/readable-stream/issues/102)
* proposal: deprecate implicit flowing of streams [#99](https://github.com/iojs/readable-stream/issues/99)
## Minutes
### adopt a charter
* group: +1's all around
### What versioning scheme should be adopted?
* group: +1’s 3.0.0
* domenic+group: pulling in patches from other sources where appropriate
* mikeal: version independently, suggesting versions for io.js
* mikeal+domenic: work with TC to notify in advance of changes
simpler stream creation
### streamline creation of streams
* sam: streamline creation of streams
* domenic: nice simple solution posted
but, we lose the opportunity to change the model
may not be backwards incompatible (double check keys)
**action item:** domenic will check
### remove implicit flowing of streams on(‘data’)
* add isFlowing / isPaused
* mikeal: worrying that we’re documenting polyfill methods – confuses users
* domenic: more reflective API is probably good, with warning labels for users
* new section for mad scientists (reflective stream access)
* calvin: name the “third state”
* mikeal: maybe borrow the name from whatwg?
* domenic: we’re missing the “third state”
* consensus: kind of difficult to name the third state
* mikeal: figure out differences in states / compat
* mathias: always flow on data – eliminates third state
* explore what it breaks
**action items:**
* ask isaac for ability to list packages by what public io.js APIs they use (esp. Stream)
* ask rod/build for infrastructure
* **chris**: explore the “flow on data” approach
* add isPaused/isFlowing
* add new docs section
* move isPaused to that section

// some bits pass through, and others are simply ignored. (That would
// be a valid example of a transform, of course.)
//
// While the output is causally related to the input, it's not a
// necessarily symmetric or synchronous transformation. For example,
// a zlib stream might take multiple plain-text writes(), and then
// emit a single compressed chunk some time in the future.
//
// Here's how this works:
//
// The Transform stream has all the aspects of the readable and writable
// stream classes. When you write(chunk), that calls _write(chunk,cb)
// internally, and returns false if there's a lot of pending writes
// buffered up. When you call read(), that calls _read(n) until
// there's enough pending readable data buffered up.
//
// In a transform stream, the written data is placed in a buffer. When
// _read(n) is called, it transforms the queued up data, calling the
// buffered _write cb's as it consumes chunks. If consuming a single
// written chunk would result in multiple output chunks, then the first
// outputted bit calls the readcb, and subsequent chunks just go into
// the read buffer, and will cause it to emit 'readable' if necessary.
//
// This way, back-pressure is actually determined by the reading side,
// since _read has to be called to start processing a new chunk. However,
// a pathological inflate type of transform can cause excessive buffering
// here. For example, imagine a stream where every byte of input is
// interpreted as an integer from 0-255, and then results in that many
// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in
// 1kb of data being output. In this case, you could write a very small
// amount of input, and end up with a very large amount of output. In
// such a pathological inflating mechanism, there'd be no way to tell
// the system to stop doing the transform. A single 4MB write could
// cause the system to run out of memory.
//
// However, even in such a pathological case, only a single written chunk
// would be consumed, and then the rest would wait (un-transformed) until
// the results of the previous transformed chunk were consumed.
