Build Status

Unleash all the numbers!!

num is an arbitrary size fixed precision library written in pure javascript. Why? Because once you write one library you want to write all the libraries.

Looking for just integers? Check out int

quick and dirty

npm install num
var num = require('num');

var foo = num('0.1').add('0.2');

// did it work?
console.log(foo.toString());
//'0.3' hell yea
