^ is the exponent operator. 2^32 means 2 to the power of 32.

Pasmal: I don't think that's the problem though, the calculation works perfectly for me on a pentium3 (500mhz) with Win98SE and an Athlon XP2400+ with WinXP Home SP1. It's a rather bizarre problem but doesn't seem to be tied to anything system related - my 2nd system seems to be pretty close to Collective's, yet he gets the problem and I don't. Strange indeed.
