LOL. yes! it's been years since I used the steps to find the accurant amount of difference. it may not have involved a %. I can only think of one concrete example. lets say that x == 15 and y == 16. Q: how much less is x than y? it is not just "1"; there was some other way of finding the answer. -- Gary Kline kl...@thought.org http://www.thought.org Public Service Unix Twenty-six years of service to the Unix community. _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
