+
+Higher level content negotiation based on [negotiator](https://www.npmjs.com/package/negotiator).
+Extracted from [koa](https://www.npmjs.com/package/koa) for general use.
+
+In addition to negotiator, it allows:
+
+- Allows types as an array or arguments list, ie `(['text/html', 'application/json'])`
+  as well as `('text/html', 'application/json')`.
+- Allows type shorthands such as `json`.
+- Returns `false` when no types match
+- Treats non-existent headers as `*`
+
+## Installation
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install accepts
+```
+
+## API
+
+<!-- eslint-disable no-unused-vars -->
+
+```js
+var accepts = require('accepts')
+```
+
+### accepts(req)
+
+Create a new `Accepts` object for the given `req`.
+
+#### .charset(charsets)
+
+Return the first accepted charset. If nothing in `charsets` is accepted,
+then `false` is returned.
+
+#### .charsets()
+
+Return the charsets that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .encoding(encodings)
+
+Return the first accepted encoding. If nothing in `encodings` is accepted,
+then `false` is returned.
+
+#### .encodings()
+
+Return the encodings that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .language(languages)
+
+Return the first accepted language. If nothing in `languages` is accepted,
+then `false` is returned.
+
+#### .languages()
+
+Return the languages that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .type(types)
+
+Return the first accepted type (and it is returned as the same text as what
+appears in the `types` array). If nothing in `types` is accepted, then `false`
+is returned.
+
+The `types` array can contain full MIME types or file extensions. Any value
+that is not a full MIME types is passed to `require('mime-types').lookup`.
+
+#### .types()
+
+Return the types that the request accepts, in the order of the client's
+preference (most preferred first).
+
+## Examples
+
+### Simple type negotiation
+
+This simple example shows how to use `accepts` to return a different typed
+respond body based on what the client wants to accept. The server lists it's
+preferences in order and will get back the best match between the client and
+server.
+
+```js
+var accepts = require('accepts')
+var http = require('http')
+
+function app (req, res) {
+  var accept = accepts(req)
+
+  // the order of this list is significant; should be server preferred order
+  switch (accept.type(['json', 'html'])) {
+    case 'json':
+      res.setHeader('Content-Type', 'application/json')
+      res.write('{"hello":"world!"}')
+      break
+    case 'html':
+      res.setHeader('Content-Type', 'text/html')
+      res.write('<b>hello, world!</b>')
+      break
+    default:
+      // the fallback is text/plain, so no need to specify it above
+      res.setHeader('Content-Type', 'text/plain')
+      res.write('hello, world!')
+      break
+  }
+
+  res.end()
+}
+
+http.createServer(app).listen(3000)
+```
+
+You can test this out with the cURL program:
+```sh
+curl -I -H'Accept: text/html' http://localhost:3000/
+```

+![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:

+
+[Node.js](http://nodejs.org):
+
+```bash
+$ npm install --save bignumber.js
+```
+
+```javascript
+var BigNumber = require('bignumber.js');
+```
+
+ES6 module (*bignumber.mjs*):
+
+```javascript
+//import BigNumber from 'bignumber.js';
+import {BigNumber} from 'bignumber.js';
+```
+
+AMD loader libraries such as [requireJS](http://requirejs.org/):
+
+```javascript
+require(['bignumber'], function(BigNumber) {
+    // Use BigNumber here in local scope. No global BigNumber.
+});
+```
+
+## Use
+
+*In all examples below, `var`, 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.*
+
+The library exports a single function: `BigNumber`, the constructor of BigNumber instances.
+
+It accepts a value of type Number, String or BigNumber,
+
+```javascript
+x = new BigNumber(123.4567)
+y = BigNumber('123456.7e-3')
+z = new BigNumber(x)
+x.isEqualTo(y) && y.isEqualTo(z) && x.isEqualTo(z)      // true
+```
+
+and a base can be specified.
+
+```javascript
+a = new BigNumber(1011, 2)          // "11"
+b = new BigNumber('zz.9', 36)       // "1295.25"
+c = x.plus(y)                       // "1306.25"
+```
+
+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)
+``` 
+
+If the limited precision of Number values is not well understood, **it is recommended to pass String values rather than Number values** to avoid a potential loss of precision.
+
+```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' 
+```
+
+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`, `toFixed` and `toPrecision` 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
+```
+
+ and a base can be specified for `toString`.
+
+ ```javascript
+ x.toString(16)                     // "ff.8"
+ ```
+
+There is also a `toFormat` 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 `config` method of the `BigNumber` constructor.
+
+The other arithmetic operations always give the exact result.
+
+```javascript
+BigNumber.config({ 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` 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` and `isFinite` 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 which applies to all BigNumber's created from it.
+
+```javascript
+// Set DECIMAL_PLACES for the original BigNumber constructor
+BigNumber.config({ 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'
+```
