javascript TypeError: Math.random is not a function on chrome

Question

I use a Math.random() function in a AngularJS Code

$scope.runFull = function () {
var rand;
    do {
        rand = Math.random();
        ...
    } while ($scope.cond < 5400); // 90 minutes         
};
$scope.runFull();

My Chrome console return javascript TypeError: Math.random is not a function

I put Math in watcher and I find Math.abs, Math.acos, Math...., Math.random, Math....

Answer 1

either Math or Math.random is overridden. run Math.random() as you first line of code and see what happens.

Answer 2

My error was : angular.module('xxxxxApp') .controller('FullController', function ($scope, $interval, xxxxService, yyyyService, ..., Math , Principal) {

YES, thank you very much everyone, I have a angularjs service named "Math".

Solution: I rename my "Math" service in "Mathematic" and I can use Math.random() :)
