I don't think you can beat Euphoria's sqrt(), even if you compromise on accuracy etc. Intel also has a machine instruction for *rounding* a f.p. number to the nearest integer. Unfortunately it can't be used directly for floor(), which always rounds *down*. Regards, Rob Craig Rapid Deployment Software http://members.aol.com/FilesEu/
