    How to set a number of decimal spaces?

    I was wandering if anyone coulda tell me how to set a 'double' to only output to 2 decimal spots only.

    For example...

    double ans;
    double a = 2;
    double b = 3;
    ans = 2/3;

    Normally, as an output, it would give me, 0.66666667... How would i make it so it only gives me 0.67 ?

    Is this a console app or a windows application?

    Actually just look at this: http://msdn2.microsoft.com/en-us/lib...be(VS.80).aspx

    hmm, it was application. But ive solved the problem...

    Code:
    y = 6.7653
    answery.Text = Convert.ToString(y= Math.Round(y,2))
