Math functions in AngularJS bindings

Question

Is there a way to use math functions in AngularJS bindings?

e.g.

The percentage is {{Math.round(100*count/total)}}%

Answer 1

The number filter formats the number with thousands separators, so it's not strictly a math function.

Moreover, its decimal 'limiter' doesn't ceil any chopped decimals (as some other answers would lead you to believe), but rather rounding them.

So for any math function you want, you can inject it (easier to mock than injecting the whole Math object) like so:

myModule.filter('ceil', function () {
  return Math.ceil;
});

No need to wrap it in another function either.
