Arithmetic operations on big numbers
BigNumber.js is a light javascript library for node.js and the browser, dealing with operations on big integers.
Include <script src="../bignumber.js"></script> in source file
The library exposes the function BigNumber( ) in the global scope, representing a factory method for generating big integer numbers. The bignumber factory can be called with an integer, a number represented as a string or another bignumber. The allowed operations are described below.
It does one thing, implementing only the main arithmetic operations for big integers,
but it does it very well and very fast
.
It is build with performance in mind and supports all basic arithmetic operations (+, -, *, /, ^, abs). Works with both positive and negative integers.
Usage
var BigNumber = require('big-number');
BigNumber(5).plus(97).minus(53).plus(434).multiply(5435423).add(321453).multiply(21).div(2).pow(2)
// 760056543044267246001
