Errrr. Which one of these would you expect to be "true"?... They're sure not equal, right? And what would make $a or $b "greater" than the other? I mean, *WHY* would you expect one of those to be "true", if you do expect one of them to be "true"? I sure can't find any logical a priori ordering, total, partial, or otherwise. Last time I checked, there was no "rule" that any set/graph or other mathematical collection had to have a defined ordering, even partial. But it's been ages since I got my Honors Math degree, so maybe they changed the rule while I wasn't looking... :-) -- brain cancer update: http://richardlynch.blogspot.com/search/label/brain%20tumor Donate: https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=FS9NLTNEEKWBE -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
