hah yeah, always worth a little skepticism, but it seemed to make some kind of sense. If you always round up or always round down, that's obviously not right and you end up losing potentially a lot of money or over-estimating the money involved.
Founding up for 5 through 9 and down for 0 through 4 seems like it makes some kind of sense, but apparently it doesn't work out that way. I'm sure someone out there knows what I'm talking about (it might be the first time, but I know I'm not making this up hah), but rounding 0.75 up to 0.8 and 0.65 down to 0.6 (or vice versa) is supposed to be more accurate or at least leads to fewer anomalies. Someone feel like writing a quick script that generates random numbers and does the rounding based on these two ideas (doing it the 'hard way') and see how much variation there is after like 10,000 iterations? If I have time later, I'll do it. Now I'm even more curious. -TG = = = Original message = = = <snip> > Supposedly this is an accounting trick that > ultimatley works out in the end for proper rounding of money > values. Yeah works out for who? Bet it doesn't for the guy paying :P ___________________________________________________________ Sent by ePrompter, the premier email notification software.
