Hi,

In my application I need to round a number to 3 decimal places. I am using
the Math.Round method which works fine. The problem I am running into is
when the number has no decimals like 5 because I need to show it as 5.000.
How can I accomplish this?

Thanks

Use a custom format string, e.g.

Console.WriteLine ("{0:0.000}", 5.5);
 
I do not want to use WriteLine. I want to do it inside my business objects.
Is there another way?

Thanks

Yes - just use String.Format using the same format string, or
yourDouble.ToString("0.000"). My code was only demonstrating the format
string to use.

the Double, Float, and Decimal datatypes' ToString() method has an
overload that takes a format string:

myVal.ToString( "0.000");
