Question

Below is the code that I am using.

I would like the output be 1.65, but I get 0.

This seems like a problem of scope. However I have declared the variable t as static, so why is the output still 0?

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        public static double t;

        private void Form1_Load(object sender, EventArgs e)
        {
            for (int i = 0; i < 100; i = i + 1)
            {
                t = (i * (1 / 60));
            }
            MessageBox.Show(Convert.ToString(t));
        }
    }
}

Answer 1

1 / 60 will always be 0.

You are doing integer division.

In a division operation, you need at least one of the operands to be double if you want a double result.

Changing:

t = (i * (1 / 60));

To:

t = (i * (1 / 60D));

Or:

t = (i * (1D / 60));

Will solve the issue.
