Angular isNumber?

you can of course use

function isNumeric(n) {
    return !isNaN(parseFloat(n)) && isFinite(n);

but here
myApp.controller('DoubleController', ['$scope', function ($scope) {
        $scope.double = function (value) {
            return (angular.isNumber(value)) ? value * 2 : null;

never works.
or am I using it wrong? https://docs.angularjs.org/api/ng/function/angular...

angular.isNumber returns true if the passed argument passes the following test:
typeof (value) === 'number'
You are most likely passing a string or some other type of data to the function.
