In a simple script consisting a single line like 
<? round(195.583,2); ?>
round() produces a proper output. However in one of my scripts, where round() is used inside a method of a sophisticated object, it gives the folowig results:
echo round(195.583, 2); -> 195
echo round(195.583, 1); -> 195
echo round(195.583, 0); -> 195
echo round(195.583, -1); -> 200
echo round(195.583, -2); -> 200

I use PHP4.2.3 with Apache 1.3.26, both of them are original Debian's binaries. I have reproduced this behaviour on several machines.
