        To infuse Math into your degree, on the off chance that  utilize it as $scope know nothing about Math.

        Least complex way, by using

    $scope.Math = window.Math;
    

          In  controller, to do this effectively would be make a Math benefit

    the best way to do this is by creating a filter

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

    then the markup looks like this:

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

    Here is an example of one of  the math function,  Math.round() function returns the value of a number rounded to the nearest integer:

    console.log(Math.round(0.9));
    // expected output: 1
    console.log(Math.round(5.95), Math.round(5.5), Math.round(5.05));
    // expected output: 6 6 5
    console.log(Math.round(-5.05), Math.round(-5.5), Math.round(-5.95));

    You have to inject Math into your scope, if you need to use it as $scope know nothing about Math.

    Simplest way, you can do

    $scope.Math = window.Math;

    in your controller. Angular way to do this correctly would be create a Math service, I guess.
