I assume you're talking about using a counter object?
Select the counter, and look in the properties panel on the left.
Click on the left-most tab.
Tick the box that says "Number of significant digits".
Also tick the box that says "Number of digits after decimal point".
Make sure the box next to it contains the value "2" (which it will by default anyway).
ahh I thought I deleted this. I found it, but thanks for the reply. It turns out I didn't have the most up to date mmf so that option wasn't available. Updated and fixed.
