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

Why not wrap the whole math obj in a filter?

var app = angular.module('fMathFilters',[]);


function math() {
    return function(input,arg) {
        if(input) {
            return Math[arg](input);
        }

        return 0;
    }
}

return app.filter('math',[math]);

and to use:

{{ number_var | math:'ceil'}}
