Display a percentage in a label

Question

I am working on a C# windows application. I have a label on my form that I want to display a calculation. Here is my code:

this.lblPercent.Text = (Convert.ToString(totalPercent));

I have the variable totalPercent defined as a double, how do I round this number to 2 decimal places?

When I run my program, 86.8245614 is being displayed in my application and I want it to display 86.82.

Or: String.Format("{0:0.00}", totalPercent);

See here for some examples of how to format numbers differently.

Here is the rounding method.

lblPercent.Text = Math.Round(totalPercent, 2).ToString();

Daniel A. White

totalPercent is a double value, so it needs to be cast to a decimal before it can be rounded.. – stuartd Apr 19 '09 at 22:09
Thanks Daniel, I was on the right track, I just had the format wrong. Thanks for your help. Susan – Apr 19 '09 at 22:11

You can try this

' Gets a NumberFormatInfo associated with the en-US culture.
Dim nfi As NumberFormatInfo = New CultureInfo("en-US", False).NumberFormat

this.lblPercent.Text = totalPercent.ToString("P", nfi)
