![decimal.js](https://raw.githubusercontent.com/MikeMcl/decimal.js/gh-pages/decimaljs.png)
An arbitrary-precision Decimal type for JavaScript.
<br>
## Features
- Faster, smaller, and perhaps easier to use than JavaScript versions of Java's BigDecimal
- Simple API but full-featured
- Replicates the `toExponential`, `toFixed`, `toPrecision` and `toString` methods of JavaScript's Number type
- Includes a `toFraction` and correctly-rounded `exp`, `ln`, `log` and `sqrt` functions
- Supports non-integer powers (although performance is limited)
- Works with numbers with or without fraction digits in bases from 2 to 64 inclusive
- Stores values in an accessible decimal floating point format
- No dependencies
- Uses JavaScript 1.5 (ECMAScript 3) features only
- Comprehensive [documentation](http://mikemcl.github.io/decimal.js/) and test set
- 8 KB minified and gzipped
![API](https://raw.githubusercontent.com/MikeMcl/decimal.js/gh-pages/API.png)
The library is similar to [bignumber.js](https://github.com/MikeMcl/bignumber.js/), but here
precision is specified in terms of significant digits instead of decimal places, and all
calculations are rounded to the precision (similar to Python's decimal module) rather than just
those involving division.
This library also adds `exp`, `ln` and `log` functions, among others, and supports non-integer powers.
Another major difference is that this library enables multiple Decimal constructors to be created
each with their own configuration (e.g. precision and range). This is, however, a significantly
larger library than *bignumber.js* and the even smaller [big.js](https://github.com/MikeMcl/big.js/).
## Load
The library is the single JavaScript file *decimal.js* (or minified, *decimal.min.js*).
It can be loaded via a script tag in an HTML document for the browser
<script src='./relative/path/to/decimal.js'></script>
or as a CommonJS, [Node.js](http://nodejs.org) or AMD module using `require`.
For Node, put the *decimal.js* file into the same directory as the file that is requiring it and use
var Decimal = require('./decimal');
or put it in a *node_modules* directory within the directory and use `require('decimal')`.
The library is also available from the [npm](https://npmjs.org/) registry
$ npm install decimal.js
To load with AMD loader libraries such as [requireJS](http://requirejs.org/):
require(['decimal'], function(Decimal) {
// Use Decimal here in local scope. No global Decimal.
});
## 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 object, `Decimal`, the constructor of Decimal numbers.
It accepts a value of type number *(up to 15 significant digits only)*, string or Decimal.
x = new Decimal(123.4567)
y = new Decimal('123456.7e-3')
z = new Decimal(x)
x.equals(y) && y.equals(z) && x.equals(z) // true
A base from 2 to 36 inclusive can also be specified.
x = new Decimal(1011, 2) // '11'
y = new Decimal('zz.9', 36) // '1295.25'
z = x.plus(y) // '1306.25'
A Decimal is immutable in the sense that it is not changed by its methods.
0.3 - 0.1 // 0.19999999999999998
x = new Decimal(0.3)
x.minus(0.1) // '0.2'
x // '0.3'
The methods that return a Decimal can be chained.
x.dividedBy(y).plus(z).times(9).floor()
x.times('1.23456780123456789e+9').plus(9876.5432321).dividedBy('4444562598.111772').ceil()
Many method names have a shorter alias.
x.squareRoot().dividedBy(y).toPower(3).equals(x.sqrt().div(y).pow(3)) // true
x.cmp(y.mod(z).neg()) == 1 && x.comparedTo(y.modulo(z).negated()) == 1 // true
Like JavaScript's Number type, there are `toExponential`, `toFixed` and `toPrecision` methods
x = new Decimal(255.5)
x.toExponential(5) // '2.55500e+2'
x.toFixed(5) // '255.50000'
x.toPrecision(5) // '255.50'
and a base can be specified for `toString`.
x.toString(16) // 'ff.8'
As mentioned above, multiple Decimal constructors can be created, each with their own independent
configuration which applies to all Decimal numbers created from it.
All calculations are rounded to the number of significant digits specified by the `precision` property
of a Decimal constructor and rounded using the rounding mode specified by the `rounding` property.
Decimal.config({ precision: 5, rounding: 4 })
D = Decimal.constructor() // constructor is a factory method
D.config({ precision: 10, rounding: 1 })
x = new Decimal(5)
y = new D(5)
x.div(3) // '1.6667'
y.div(3) // '1.666666666'
Decimal.precision // 5
D.precision // 10
Many of the methods of JavaScript's Math object are replicated as static methods of a Decimal constructor
Decimal.sqrt('6.98372465832e+9823') // '8.3568682281821340204e+4911'
Decimal.pow(2, 0.0979843) // '1.0702770511687781839'
There is a `toFraction` method with an optional *maximum denominator* argument
y = new Decimal(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 `Decimal` values.
x = new Decimal(NaN) // 'NaN'
y = new Decimal(Infinity) // 'Infinity'
x.isNaN() && !y.isNaN() && !x.isFinite() && !y.isFinite() // true
The value of a Decimal is stored in a decimal floating point format in terms of a coefficient, exponent and sign.
x = new Decimal(-123.456);
x.c // '1,2,3,4,5,6' coefficient (i.e. significand)
x.e // 2 exponent
x.s // -1 sign
For further information see the [API](http://mikemcl.github.io/decimal.js/) reference in the *doc* directory.
## Test
The *test* directory contains the test scripts for each method.
The tests can be run with Node or a browser.
To test a single method use, from a command-line shell in the root directory, for example
$ node test/toFraction
To test all the methods
$ node test/every-test
or
$ npm test
For the browser, see *single-test.html* and *every-test.html* in the *test/browser* directory,
## Build
For Node, if [uglify-js](https://github.com/mishoo/UglifyJS2) is installed
npm install uglify-js -g
then
npm run build
will create *decimal.min.js*.
The *decimal.min.js* already present was created with *Microsoft Ajax Minifier 5.8*.

For help:
$ node bigtime -h
Usage example:
Compare the time taken by the Decimal plus method and the BigDecimal add method.
Time 10000 calls to each.
Use operands of up to 40 random digits (each unique for each iteration).
Check that the Decimal results match the BigDecimal results.

NOTES:
ICU4J
=====
IBM java package: com.ibm.icu.math.
pow's argument must be a BigDecimal.
This javascript version is used by the gwt_math project.
Among other differences, doesn't have .toPlainString() or .stripTrailingZeros().
Exports BigDecimal only.
Much faster than gwt on Firefox, on Chrome it varies with the method.
