Hello,

Try This:
$scope.total = function(){

var total = 0;

angular.forEach($scope.invoice.items, function(item){

total += item.qty * item.price;

})

return total.toFixed(2);

}

});

let's try this also, Just for an suggestion, You can use this same scenario in everywhere, So declare like this. It will use globally for your project just pass an argument like value and number of degits.
function roundNumbers(decimalValue,noOfDigit){
     return decimalValue.toFixed(noOfDigit);
}
Separation of concerns is essential for reusable coding.

For more reference.

//total array total

$scope.total = function () {

var total = 0;

angular.forEach($scope.myData, function (invoice) {

total += invoice.total;

})

return total.toFixed(2);

}

//Addition of 2 numbers in Item row

$scope.AddNumbers1 = function (i) {

var a = Number($scope.qty || 0);

var b = Number($scope.price || 0);

$scope.total = (a + b).toFixed(2);

}

If i wrap code in both scenarios at that time total array value ins not displaying

I need decimal float value in both item row and entire array total

Hi Mahesh,

$scope.total = function(){
var total = 0;
angular.forEach($scope.invoice.items, function(item){
total += item.qty * item.price;
})
return total.toFixed(2);
}

use toFixed() function.

Thank you.
