BigNumber.js

Forked from alexbardas/bignumber.js (http://alexbardas.github.io/bignumber.js/) to add handling for binary operators and HEX values.

BigNumber.js is a light javascript library for node.js and the browser. It supports arithmetic operations on Big Integers.

It is build with performance in mind, uses the fastest algorithms and supports all basic arithmetic operations (+, -, *, /, %, ^, abs). Works with both positive and negative big integers.

: (http://xactant.github.io/bignumber.js/)

Support for basic binary operation (AND, OR, XOR) and enable creation of BigNumbers from hex values passed in as strings (i.e. "0xFF" or "0xff" is processed as 255);

Install: npm install

Test: npm test

Usage:

• in node:

	var BigNumber = require('big-number');

    BigNumber(5).plus(97).minus(53).plus(434).multiply(5435423).add(321453).multiply(21).div(2).pow(2);
    // 760056543044267246001

• in the browser:

	<script src ="big-number.js"></script>

    n(5).plus(97).minus(53).plus(434).multiply(5435423).add(321453).multiply(21).div(2).pow(2);
    // 760056543044267246001
