Rounding in Note

Ok.  So i have two parameters:

&Over_Shaft = .4649
&Over_Shaft_Tol = .0005

I'm inserting a note into my part by doing a "insert annotation
feature"->"add"->"note"  and type something like:

<diam-symbol>&Over_Shaft <plusminus-symbol>&Over_Shaft_Tol

but.  What appears on my screen is:

<diam>.465 <+->.001

How do I force Pro/e to use 4 place in a note?

Thanks!
