Feature Request: Add number formatting filters

[someone1]

Maybe something like: http://www.mredkj.com/javascript/nfbasic.html

or from AngularJS: https://docs.angularjs.org/api/ng/filter/number / https://docs.angularjs.org/api/ng/filter/currency

Seems like a legit request. Will add when time allows.

should these all be separate filters or will there be libraries of filters? i.e. How granular should each filter be?

[addyosmani]

I would prefer to have each filter kept in an individual file to make it super easy to locate, document and test. Interested in helping port over any of these?

@addyosmani Will a number filter be added to this any time soon?
