An arbitrary-precision arithmetic library for JavaScript.

Installation

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. Although the wiki describes the Java version, the JavaScript version uses almost the same methods for BigInteger, ExtendedDecimal, and ExtendedFloat.
