计算小数

Question

我设法计算变量，但我的问题是我如何用小数计算数字?

int Var1;
int Var2;
int Uitkomst;
Var1 = Convert.ToInt16(txtGetal1.Text);
Var2 = Convert.ToInt16(txtGetal2.Text);
Uitkomst = Var1 * Var2;
txtUitkomst.Text = "Uitkomst:" + Uitkomst.ToString();

Answer 1

您应该声明您的Var1和Var2，您可以使用double.Parse()来转换用户输入

我把你的代码改成了:

double Var1;
double Var2;
double Uitkomst;
Var1 = double.Parse(txtGetal1.Text);
Var2 = double.Parse(txtGetal2.Text);
Uitkomst = Var1 * Var2;
txtUitkomst.Text = "Uitkomst:" + Uitkomst.ToString();
