robust-split

Use this package when you want to split a double precision floating point number into a 2-part non-overlapping sequence.

Why would you ever want to do that? Well these sequences are an efficient way to perform
_exact_ mathmatical operations on numbers in javascript.

install

npm install robust-split

If you want to use this in the browser, check out browserify

use

``javascript

var rsplit = require('robust-split');

var p = rsplit(0.3);

console.log(p); //[ 2.980232227667301e-9,
// 0.29999999701976776 ]
`

You could then pass the sequence into robust-estimate-float

`javascript
var num = require('robust-estimate-float');

var r = num(p);

console.log(r) // 0.3
``
