How to Display the Actual Number with Decimal

When you configure how numbers display, you select the number of decimal places to show. Crystal Reports then rounds the display value to that decimal position and that is what you see. 

But what if you want to display the actual number? If the original number has no decimal places, you want to see that. If the original has three decimal places, you want to see all three.

You can do this using conditional formatting.
