I am developing a project in which the result of the division of the 5 items always 0, someone can help me to tidy up

private void btnCalcu_Click(object sender, EventArgs e)
    {
        //convertendo
        Total = Convert.ToInt32(txtFechado.Text); 
        SemInt = Convert.ToInt32(txtSemInt.Text);
        LigDepois = Convert.ToInt32(txtLigaDps.Text);
        Negoc = Convert.ToInt32(txtNegoc.Text);
        Agend = Convert.ToInt32(txtAgend.Text);

        //Calculando

        totalLig = Total + SemInt + LigDepois + Negoc + Agend;
        porc = (Total/100) * totalLig;
        TotPoc = Convert.ToDouble(porc);
        MessageBox.Show("Total de ligações é: " + totalLig + " Pocentual é : " +TotPoc );



    }

  • This will not be related to the values you are using in the calculation?

  • @Joãomartins, the TotPoc no, but the totalLig yes that is strange, I do not know if I am wrong in the logic of the account or what

  • Edit your question and put the example values you are using, maybe this way we can come up with a solution?

When you make a division between two integers (int), the result will be integer..

ex: 8 / 10 = 0

if you want 0.8 you will have to convert one of the values to double, or another type that accepts decimal values..

ex: 

double TotPoc = ((double)Total/100) * totalLig;

Since you use the 100 can use the suffix D

would look like this:

  double TotPoc = (Total/100D) * totalLig;

Another thing would be when receiving values from the user would be to use the int.Tryparse instead of Convert.ToInt32
