IAC, AFAICS, we've established that an unsigned int isn't a good choice since it offers no benefits and may, in some circumstances, be less useful in that (a) it's not CLS compliant and (b) it may not be storable in some databases.

Thanks, so basically, the current formula is OK and can return negative values, which would then be normal.

So, this whole thread that you exchanged with Gregory was about the possibility to always return a positive value, which would then be not polynomal PKZip CRC32 compliant. Is that it?
