hi,
the current behavious is "more connect" than the old one.
we automagiacally propagate from in to float in the conversion
routines once we gent an overflow. to get the "old" bahaviour
in your case you need to case the result of hexdec() to int:
$dec = (int) hexdec($hex);
and you'll get the old behaviour back. i do think that
normally you don't want negative results from hexdec() so the
new behaviour is "more correct".
