sumi-math

A lightweight mathematics library as a replacement for the internal Math object.

Target environments

• IE 6+
• Latest Stable: Firefox, Chrome, Safari, Opera
• Node.js & other non-browser environments or browser extensions

Quick start

Four quick start options are available:

• Download the latest release
• Clone the repo: git clone https://github.com/rainersu/math.git
• Install with Bower: bower install sumi-math
• Install with npm: npm install sumi-math

Example use

Including in a browser:

<script type='text/javascript' src='/path/to/sumi-math-1.0.3.min.js'></script>
<script type='text/javascript'>
var x = Arith.parseFloat('xxx-123.3%xxx', true);  // x = -1.233
</script>

As a module that works with AMD(e.g., RequireJS):

define(['/path/to/sumi-math-1.0.3.min.js'], function(Arith) {
	var x = Arith.round(55.549, -2);   //  x = 55.55
});

Including in a CommonJS environment(e.g., Node.js):

var sumiMath = require('/path/to/sumi-math');
var x = sumiMath.toPercent(-0.123, 2);   // x = -12.30%

Build from source

First, you need to have Node.js and Grunt installed.

$ git clone git@github.com:rainersu/math.git
$ npm install -g grunt-cli
$ cd math
$ npm install
$ grunt

It provides compiled JS (sumi-math.*), as well as compiled and minified JS (sumi-math.min.*). JS source maps (sumi-math.*.map) are available for use with certain browsers' developer tools.
