Please see the angularjs example

https://docs.angularjs/api/ng/filter/number

By the way ,suggest not mix asp and angularjs code into the same tag

 //number with two digit
 Negative number: <span>{{-val | number:2}}</span>

You can try javascript toFixed method like below

{{((qty * price )/100  * 5).toFixed(2)}}

you can try

<asp:TextBox runat="server" Text='{{(qty * price )/100  * 5 | number:2}}' ReadOnly="true"/>

angularjs document contains a very simple and pretty example. You can do this by :

<script>
  angular.module('numberFilterExample', [])
    .controller('ExampleController', ['$scope', function($scope) {
      $scope.val = 1234.56789;
    }]);
</script>
<div ng-controller="ExampleController">
  <label>Enter number: <input ng-model='val'></label><br>
  Default formatting: <span id='number-default'>{{val | number}}</span><br>
  No fractions: <span>{{val | number:0}}</span><br>
  Negative number: <span>{{-val | number:4}}</span>
</div>
