I have a form that has a field filled with value from the database. In this form, I have to make 2 percentage accounts, take these two values to add and finally get the start value and subtract from the sum of the percentages.

I set up the fields, but javascript could not work. Can it be with JQuery ?

$("#percentual1").change(function () {
                    var valor = $("#valor").val();                     
                    var resultado1 = valor * (parseInt($(this).val()) / 100);
                    var resultado1Arrendodado = parseFloat(resultado1.toFixed(2));
                    $("#valor1").val(resultado1Arrendodado);
                    var ValorFinal1 = parseFloat($('#valor1').val());
                    var Valor1Arrendodado = parseFloat(ValorFinal1.toFixed(2));
                    var Valor2 = parseFloat(0.00);
                    var TotalSobra = Valor1Arrendodado + Valor2;
                    if (Number.isNaN(TotalSobra)) {
                        TotalSobra = 0;
                        $('#valorSobra').val(TotalSobra);
                    } else {
                        $('#valorSobra').val(TotalSobra);
                    }
                });
                $("#percentual2").change(function () {
                    var valor = $("#valor").val();
                    var resultado2 = valor * (parseInt($(this).val()) / 100);
                    var resulado2Arrendodado = parseFloat(resultado2.toFixed(2));
                    $("#valor2").val(resulado2Arrendodado);
                    var Valor1 = parseFloat($('#valor1').val());
                    var Valor1Arrendodado = parseFloat(Valor1.toFixed(2));
                    var Valor2 = parseFloat($('#valor2').val());
                    var Valor2Arrendodado = parseFloat(Valor2.toFixed(2));
                    var TotalSobra = Valor1Arrendodado + Valor2Arrendodado;
                    if (Number.isNaN(TotalSobra)) {
                        TotalSobra = 0;
                        $('#valorSobra').val(TotalSobra);
                    } else {
                        $('#valorSobra').val(TotalSobra);
                    }
                });

As said in the comment .toFixed (2) adding the toFixed it will round the value.

Here is the working code.

$("#percentual1").change(function () {
                    var valor = $("#valor").val();                     
                    var resultado1 = valor * (parseInt($(this).val()) / 100);
                    var resultado1Arrendodado = parseFloat(resultado1.toFixed(2));
                    $("#valor1").val(resultado1Arrendodado);
                    var ValorFinal1 = parseFloat($('#valor1').val());
                    var Valor1Arrendodado = parseFloat(ValorFinal1.toFixed(2));
                    var Valor2 = parseFloat(0.00);
                    var TotalSobra = Valor1Arrendodado + Valor2;
                    if (Number.isNaN(TotalSobra)) {
                        TotalSobra = 0;
                        $('#valorSobra').val(TotalSobra);
                    } else {
                        $('#valorSobra').val(TotalSobra);
                    }
                });
                $("#percentual2").change(function () {
                    var valor = $("#valor").val();
                    var resultado2 = valor * (parseInt($(this).val()) / 100);
                    var resulado2Arrendodado = parseFloat(resultado2.toFixed(2));
                    $("#valor2").val(resulado2Arrendodado);
                    var Valor1 = parseFloat($('#valor1').val());
                    var Valor1Arrendodado = parseFloat(Valor1.toFixed(2));
                    var Valor2 = parseFloat($('#valor2').val());
                    var Valor2Arrendodado = parseFloat(Valor2.toFixed(2));
                    var TotalSobra = Valor1Arrendodado + Valor2Arrendodado;
                    if (Number.isNaN(TotalSobra)) {
                        TotalSobra = 0;
                        $('#valorSobra').val(TotalSobra.toFixed(2));
                    } else {
                        $('#valorSobra').val(TotalSobra.toFixed(2));
                    }
                });
