I'm running 5.2.3. Reaction on above discussion: of course this problem can
be solved with all sorts of solutions, but my question is: is it good that a
function returns a number that doesn't exist? I once posted a bug report
about a wrong round()-result, though it wasn't a bug, but a

Some information from Wikipedia: http://en.wikipedia.org/wiki/Negative_zero.
Says in math a negative zero doesn't exist, in computing it does. Strange
thing is that PHP4 and 5 until at least 5.1.6 (see Jim Lucas) round() gives
a float(0) and then 5.2.3 gives float(-0). I'll report a bug.

I've always questioned the round() function.

For downward rounding, you'd always want to use floor() and use ceil() for
rounding up. round() rounds up on a 5, down on a 4 and below.
Example:
echo round(141.074, 2); // 141.07
