How about
Use integer; $thevalue*=1;
Seems the simplest, IMHO. It rounds everything down, btw - so it acts kinda like 'div' in PASCAL. That's where it's useful. For rounding to the nearest, use any of the above.

    I think you mean int?(been a while since I used pascal). Div was the divisor operation. The result being not a rounded down number, but the divisor of the operation. as in: 5 div 2 = 2 meaining 5/2 = 2 remainder 1 . Div returns the 2, Mod returns the 1. Admittedly this is irrelivant to the origonal question, but... :)
