Node.JS wrapper around a pure javascript BigInteger Library

BigInt Node

This is a Node.JS port of the pure Javascript Big Integer library created by Leemon Baird.

It doesn't export all functions as of yet (mostly the crypto related ones are missing ), but exports most of those needed to simply use Big Integers. Where possible, this wrapper does its best to ensure that unsafe functions in the original library have been removed.

Usage

BigInt = require 'bigint-node'

large = BigInt.ParseFromString("1232223582030304828202",10)
smaller = BigInt.FromInt(124442255)

large.modEquals(smaller)

console.log large.toStr(10)
# 82641132
