If you get a result of "1,234.56" from number_format() and try to use that as a numerical value (i.e. it's converted to an int or float), you'll end up with the value being 1, though. Everything after the first non-numeric character is lost. That's what he's talking about. ---John Holmes... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
