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

That doesn't look like a very Angular way of doing it. I'm not entirely sure why it doesn't work, but you'd probably need to access the scope in order to use a function like that.

My suggestion would be to create a filter. That's the Angular way.

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

Then in your HTML do this:

The percentage is {{ (100*count/total) | ceil }}%
