sum of values with ng-repeat

Question

Good night

I’m having a problem adding up values with ng-repeat

Object 1

COMISSAO_CORRETOR: "5.0"
CPF_CONTRATO: "xxx.xxx.xxx-xx"
NUMERO_CONTRATO: "1234567"
VALOR_BRUTO: "70000.00"
VALOR_COMISSAO: "3500.00"
VALOR_LIQUIDO: "70000.00"

Object 2

COMISSAO_CORRETOR: "5.0"
CPF_CONTRATO: "xxx-xxx-xxx-xx"
NUMERO_CONTRATO: "98765442"
VALOR_BRUTO: "10000.00"
VALOR_COMISSAO: "500.00"
VALOR_LIQUIDO: "10000.00"

I’m trying to add the VALO_COMISSAO and I’m using the following function

FUNCTION

$scope.GetTotal = function () {
  var total = 0;
    for(var i = 0; i < $scope.relatorios.length; i++){
        var relatorio = $scope.relatorios[i];
        total += (relatorio.VALOR_COMISSAO);
    }
    return total;

}

But the total is being returned like this 03500.00500.00

Answer 1

Convert your String (report.VALOR_COMISSAO) to Float, once its attribute is in string it is concatenating the values.

$scope.GetTotal = function () {
  var total = 0;
    for(var i = 0; i < $scope.relatorios.length; i++){
        var relatorio = $scope.relatorios[i];
        total += parseFloat(relatorio.VALOR_COMISSAO);
    }
    return total;
}

Answer 2

Remove double quotes from the commission value attribute, did it work? Angularjs, as well as other frameworks and Javascript, recognize double quotes as a String and not a numerical value for performing mathematical operations.

Or use parseFloat if the value is always received as String and double quotes.
