countUp.js

countUp.js is a dependency-free, lightweight JavaScript "class" that can be used to quickly create animations that display numerical data in a more interesting way.

Despite its name, countUp can count in either direction, depending on the startVal and endVal params that you pass. Bower and Component .json files are included, as well as a coffeescript version, thanks to @HHSnopek.

countUp.js supports all browsers.

var numAnim = new countUp("SomeElementYouWantToAnimate", 24.02, 99.99, 2, 1.5);

with optional callback:
