Re: very confused....hex to decimal

you nailed it on all accounts, pretty much.

by the way, the reason i know it should be 685630.9500000000 is that i can use a few other
programs (that i didn't write, <g>) that correctly extract the information. it's a UTM x
coordinate. i'm using the other programs to confirm my results.
