In this article, we will see how to convert a string into a number in AngularJS, along with understanding its implementation through the illustrations.
Approach:
Example 1: In the first example, the string ’90’ is converted to an integer.
HTML
<!DOCTYPE HTML>
< html >
< head >
< script src =
</ script >
< script >
var myApp = angular.module("app", []);
myApp.controller("controller", function ($scope) {
$scope.a = '90';
$scope.isNumberA = angular.isNumber($scope.a);
$scope.convertToInt = function () {
$scope.a = parseInt($scope.a);
$scope.isNumberA = angular.isNumber($scope.a);
};
});
</ script >
</ head >
< body style = "text-align:center;" >
< h1 style = "color:green;" >

< div ng-app = "app" >
< div ng-controller = "controller" >
Value = {{a}}
< br >< br >
< button ng-click = 'convertToInt()' >
Click to convert
</ button >
< br >< br >isNumber(value) - {{isNumberA}}
</ div >
</ div >
</ body >
</ html >

Output:
Example 2: The 2 strings are added and then converted to an integer and then added again.
HTML
<!DOCTYPE HTML>
< html >
< head >
< script src =
</ script >
< script >
var myApp = angular.module("app", []);
myApp.controller("controller", function ($scope) {
$scope.a = "10";
$scope.b = "20";
$scope.strToInt = function () {
$scope.a = parseInt($scope.a);
$scope.b = parseInt($scope.b);
};
});
</ script >
</ head >
< body style = "text-align:center;" >
< h1 style = "color:green;" >
