jquery.counterup
==========

jquery.counterup is a jQuery plugin that *animates* a number from zero (counting up towards it). It supports counting up:

* integers `12345`
* floats `0.1234`
* formatted numbers `1,234,567.00`
* time `21:45:00`

Features:

* Auto-detect for integers, floats or formatted numbers.
* The plugin will also use the number of decimal places the original number is using.
* Start counter with a different duration and delay by setting `data-counterup-time=""` and `data-counterup-delay=""`.
* Lets you use your own formatter.
* Lightweight: ~1kb
* Minimal setup

*Requires [waypoints.js](http://imakewebthings.com/jquery-waypoints/)*

`delay` - The delay in milliseconds per number count up

`time` - The total duration of the count up animation

`offset` - The viewport percentile from which the counter starts (by default it's 100, meaning it's triggered
at the very moment the element enters the viewport)

`beginAt` - The number from which to count up

`formatter` - A callback to format the number with
