The problem is in the way that real numbers are implemented. If you do some searches, you'll find many, many discussions of this. Simple fact is that the behaviour under these circumstances is not what you think it is. This kind of thing is the reason that most languages have high-precision floating point libraries available. -- Bill Moran Collaborative Fusion Inc. _______________________________________________ email@example.com mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
