+![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.
+

+    npm install uglify-js -g
+
+then
+
+    npm run build
+
+will create *bignumber.min.js*.

+> _Deprecation notice:_
+> Consider [jsdom-global](https://github.com/rstacruz/jsdom-global) instead, a simpler alternative that also works outside of Mocha. `mocha-jsdom` still works, but `jsdom-global` is better supported.
+
+---
+
+# mocha-jsdom
+
+> Test frontend libraries in the console using Node.js, [mocha] and [jsdom]. 
+
+[![Status](https://travis-ci.org/rstacruz/mocha-jsdom.svg?branch=master)](https://travis-ci.org/rstacruz/mocha-jsdom "See test builds")
+
+<br>
+
+## Usage
+
+```sh
+$ npm i --save-dev mocha-jsdom
+```
+
+[![npm version](http://img.shields.io/npm/v/mocha-jsdom.svg?style=flat)](https://npmjs.org/package/mocha-jsdom "View this project on npm")
+
+Use `jsdom()` inside your `describe(...)` block (or the global context). It will 
+turn your Node.js environment into a mock browser environment supporting the 
+full DOM and browser API. The variables `window`, `document`, `history` (and so 
+on) will then be available for use.
+
+```js
+var jsdom = require('mocha-jsdom')
+var expect = require('chai').expect
+
+describe('mocha tests', function () {
+
+  jsdom()
+
+  it('has document', function () {
+    var div = document.createElement('div')
+    expect(div.nodeName).eql('DIV')
+  })
+
+})
+```
+
+See [examples/basic](examples/basic) for an example of a basic setup.
+
+<br>
+
+## Upgrading to v2.0.0
+
+If you are coming from mocha-jsdom v1.x, remove `jsdom` if you're not using it before upgrading. `jsdom` is now a direct dependency of `mocha-jsdom`.
+
+```bash
+# using Yarn
+yarn remove jsdom
+yarn upgrade mocha-jsdom
+```
+
+```bash
+# using npm
+npm uninstall -S -D jsdom
+npm upgrade mocha-jsdom
+```
+
+<br>
+
+## Node and io.js information
+
+As of jsdom 4.0.0, [jsdom now requires io.js](https://github.com/tmpvar/jsdom/blob/master/Changelog.md#400) and will not work with Node.js 0.12 or below.
+
+<br>
+
+## How it works
+
+mocha-jsdom is a simple glue to integrate [jsdom] to mocha.
+
+Invoking `jsdom()` will inject `before` and `after` handlers to the current 
+mocha suite which will setup and teardown jsdom. Here's what it does:
+
+* __Window__: `global.window` will be available as the jsdom.
+
+* __Globals__: global variables like `document` and `history` are propagated, 
+  and they're cleaned up after tests run.
+
+* __Error handling__: jsdom errors are sanitized so that their stack traces are 
+shortened.
+
+__NB:__ Before you try this library, learn about jsdom first. In fact, you may be 
+able to integrate jsdom into your tests *without* this library; this is mostly 
+syntactic sugar and reasonable defaults.
+
+<br>
+
+## Using with a library
+
+Perfect for testing small DOM-consuming utilities in the console. See 
+[test/jquery.js](test/jquery.js) for an example.
+
+```js
+describe('mocha tests', function () {
+
+  var $
+  jsdom()
+
+  before(function () {
+    $ = require('jquery')
+  })
+
+  it('works', function () {
+    document.body.innerHTML = '<div>hola</div>'
+    expect($("div").html()).eql('hola')
+  })
+
+})
+```
+
+See [examples/basic](examples/basic) for an example of a basic setup.
+
+<br>
+
+## Using with a library, alternate
+
+You can also pass the source code via `src`:
+
+```js
+describe('mocha tests', function () {
+  jsdom({
+    src: fs.readFileSync('jquery.js', 'utf-8')
+  })
+
+  ...
+})
+```
+
+<br>
+
+## Configuration
+
+You can pass jsdom options:
+
+```js
+describe('mocha tests', function () {
+  jsdom({
+    parsingMode: 'xml'
+  })
+
+  ...
+})
+```
+
+<br>
+
+## Working with mocha --watch
+
+When using with `--watch`, you my encounter strange errors from 3rd-party
+libraries like jQuery not working properly.
+
+In these cases, use `require('mocha-jsdom').rerequire` instead of `require()`.
+This will ensure that the `require()` call will always happen.
+
+```js
+var $
+var jsdom = require('mocha-jsdom')
+var rerequire = jsdom.rerequire
+
+jsdom()
+
+before(function () {
+  $ = rerequire('jquery')
+})
+```
+
+<br>
+
+## Special config
+
+Other mocha-jsdom specific options:
+
+ * `globalize` - propagates to values in `window` to `global`. defaults to true.
+
+ * `console` - allows you to use `console.log` inside a jsdom script. defaults 
+ to true.
+
+ * `useEach` - bind to Mocha's `beforeEach`/`afterEach` rather than `before`/`after`.
+ defaults to false.
+
+ * `skipWindowCheck` - skips checking of `window` at startup. When false,
+ mocha-jsdom will throw an error if `window` already exists. Defaults to false.
+
+[jsdom]: https://www.npmjs.org/package/jsdom
+[mocha]: https://www.npmjs.com/package/mocha
+
+<br>
+
+## Testling support
+
+Yes, fully compatible with testling. A test suite using jsdom should be able to use testling.
+
+See [examples/basic](examples/basic/) for a setup that allows for testing via iojs (jsdom), testling, and mocha via the browser.
