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

Better option is to use :

{{(100*score/questionCounter) || 0 | number:0}}

It sets default value of equation to 0 in the case when values are not initialized.
