math-helpers

Tiny statistics helper lib for node and the browser. Robust and fast.

Installation

npm install math-helpers

(or just download math-helpers.js if you want to use it in the browser)

Usage

Node (or with browserify)

var math = require('math-helpers')(/* options */)

var avg = math.avg([1, 2, 3])
// TODO: document the other methods

Browser:

AMD (with a script load like require.js)

define(['path/to/math-helpers'], function (mh) {
  var math = mh(/* options */)

  // use it...
})

Old and busted script tag (seriously, you shouldn't to that anymore :-P)

<script src="fancy://cdn.com/math-helpers.js"></script>
<script>
  var math = window.MathHelpers(/* options */)
</script>

Options

You can pass some options to the module.

{
  precision: 3 // results will be rounded to this number of decimals
}
