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

While the accepted answer is right that you can inject Math to use it in angular, for this particular problem, the more conventional/angular way is the number filter:

The percentage is {{(100*count/total)| number:0}}%

You can read more about the number filter here: http://docs.angularjs.org/api/ng/filter/number
