Description:
------------
We have a report on http://bugzilla.wikimedia.org/show_bug.cgi?id=7013 that in PHP 4.4.3 on linux, integer conversion rounds to the nearest integer. This is a change from the previous behaviour, according to the manual and in previous versions of PHP, integer conversion rounds down. I don't see anything about this in the changelog, so I'm assuming the problem persists in 4.4.4. 

Reproduce code:
---------------
intval(0.99)

Expected result:
----------------
0

Actual result:
--------------
1

# php -r 'var_dump(intval(0.9));'
int(0)
# php -v
PHP 4.4.5-dev (cli) (built: Aug 22 2006 21:48:33) (DEBUG)

Same result with 4.4.4, 4.4.3 and others.
Obviously such change could not happen, 'cause it would break lots of tests.

I couldn't confirm this personally, I tried a new build of 4.4.3 and 4.4.4 on linux, but didn't see the bug on either. Perhaps someone here has an idea about how to reproduce it?

I guess you should ask the person who originally reported it.
