AngularJS forEach and adding values

Question

var grandTotal;
angular.forEach($scope.gear, function(value, key) {
    var rowTotal = value.amount * value.price;
    console.log(rowTotal);
    grandTotal += rowTotal; 
});
console.log('grandTotal: '+grandTotal);

I have the above that I'm trying to get a grant total for, It seems to return NaN for my grandTotal

UPDATE:

var grandTotal = 0;
angular.forEach($scope.gear, function(value, key) {
    var rowTotal = value.amount * value.price;
    rowTotal = rowTotal.toFixed(1);
    console.log(rowTotal);
    grandTotal += rowTotal;
});
console.log('grandTotal: '+parseFloat(grandTotal));

this returns enter image description here

I guess your grandTotal variable was not initialized :) So grandTotal += rowTotal will result in nan. Use var grandTotal = 0; — guru
