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 easiest way to do simple math with Angular is directly in the HTML markup for individual bindings as needed, assuming you don't need to do mass calculations on your page. Here's an example:

{{(data.input/data.input2)| number}} 

In this case you just do the math in the () and then use a filter | to get a number answer. Here's more info on formatting Angular numbers as text:
