It depends on how he is actually handling his magnifications whether that will be ok or not. The only wrapping he would have to be careful of is if he really is approaching the real boundaries for the data type he's actually using - don't go beyond 0 or 4,294,967,295 or unsigned int, and don't go beyond -2,147,483,648 or 2,147,483,647 for signed int. But then again, maybe he wants the magnification to wrap around in the user's face after awhile :-) Gambit
