Strange rounding behavior

  Asked By: Conrad    Date: Oct 28    Category: Asp.net    Views: 2670

I'm having a very odd problem with .Net implicit rounding.
I'm trying to show an accurate percentage in a label control.

decimal rounded = Math.Round(Convert.ToDecimal(((totalCrashes * 100) / 60)), 1);

where totalCrashes == 1

I would like to return 1.6 from rounded, but I get 1.

I want to be able to show:

CrashLabel.Text = rounded.ToString("p")

and have it show: 1.6%

You need to divide by 60.0 with just 60 the result is an integer divide.
I would also change 100 to 100.0

Haven't done much .Net arithmetic, yet.
Never would have thought thought of
your solution. Works perfectly.
