Question

I can’t get this to divide into a decimal. It is rounding to value 0.

    private void button24_Click(object sender, EventArgs e)
    {
        double x = 0;

        x = 1 / 2;

        ans.Text = x.ToString();
    }

When I debug, x is zero before it is sent to the textbox ‘ans.’

I tried..and string variable is still zero..

double x = 1/5;

string displayX = x.ToString("0.0000");

Answer 1

It’s integer division and those are the expected outputs.

double x = 1.0 / 5;  // this will not perform integer division
double x = 1/5;  // this does  (1/5 = 0).  
double x = 1D / 5; // this will not because 1 is treated as a double
