+![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.
+

+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.

+### 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.
