An arbitrary-precision arithmetic library for JavaScript.

Demo: [https://peteroupc.github.io/BigNumber/demo/](https://peteroupc.github.io/BigNumber/demo/)

Installation

--------------

[![NPM](https://nodei.co/npm/bignumber-poupc.png)](https://www.npmjs.com/package/bignumber-poupc/)

To install, run the following:

    npm install peteroupc/BigNumber

or

    npm install bignumber-poupc

You may need to install the latest version of Node.js or use `npm` version 1.3.15 or later.

Usage

--------------

    var bn=require("bignumber-poupc"),

          BigInteger=bn.BigInteger,

          ExtendedDecimal=bn.ExtendedDecimal,

          ExtendedFloat=bn.ExtendedFloat;

    var num=BigInteger.valueOf(2000);

For API documentation, see the [CBOR-Java wiki](https://github.com/peteroupc/CBOR-Java/wiki).

Although the wiki describes the Java version, the JavaScript version uses almost

the same methods for BigInteger, ExtendedDecimal, and ExtendedFloat.
