Thanks Rob, My misgivings revolved around using string concatenation to create numbers. Not misgivings, really. just the suspicion that there should be a way to handle numbers as numbers from start to finish--e.g., something roughly the opposite of POSIX::frexp()--and the nagging feeling that I'd missed something obvious. --j -------------------------------------------------- This email and attachment(s): [ ] blogable; [ x ] ask first; [ ] private and confidential daggerquill [at] gmail [dot] com http://www.tuaw.com http://www.downloadsquad.com http://www.engatiki.org values of β will give rise to dom!
