Restricting number to 2 decimal places in HTML file with AngularJS
Question
I have a HTML page that displays the information from an AngularJS controller. This is part of the code:
<td id="calories">{{ ctrl.caltotal }}</td>
My question is, what do I need to do so that this is displayed at a maximum of 2 decimal places? At the moment if I change the program it can give values like 23.00000004. Is this a change that should be made in the Angular Controller or in the HTMl view? Thanks.

<td id="calories">{{ ctrl.caltotal | number:2}}</td>
它将限制在两个小数位。

Consider the following code :
<html>
<head>
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.4.8/angular.min.js"></script>
<style>
</style>
</head>
<body ng-app="myApp" ng-controller="myCtrl">
<input type="number" ng-model="score" /> {{score | number:2}}
<script>
//1 module declaration
var app = angular.module('myApp', []);
//2 controller declaration
app.controller('myCtrl',function($scope){
$scope.score = 50;
//code here
});
</script>
</body>
</html>

UPDATE
Check out DecimalPipe ( https://angular.io/api/common/DecimalPipe ).
{{ your_number | number : '1.0-2' }}
'1.0-2' represents {minIntegerDigits}.{minFractionDigits}-{maxFractionDigits}
minIntegerDigits: The minimum number of integer digits before the decimal point. Default is 1.
minFractionDigits: The minimum number of digits after the decimal point. Default is 0.
maxFractionDigits: The maximum number of digits after the decimal point. Default is 3.
