It's not really documented, that I've seen. I'll put this on my todo list. There was a discussion about this in March/April of last year. In short, it's not easily fixable. Christian Seiler's post on 2009-04-07 is very interesting. The MARC archive split the thread in two: http://marc.info/?t=123704116800002&r=1&w=2 http://marc.info/?t=123865732900002&r=1&w=2 I imagine the workarounds are the BC Math and GMP functions. --Dan -- T H E A N A L Y S I S A N D S O L U T I O N S C O M P A N Y data intensive web and database programming http://www.AnalysisAndSolutions.com/ 4015 7th Ave #4, Brooklyn NY 11232 v: 718-854-0335 f: 718-854-0409 -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
