New Comment:
Floating point values have a limited precision. Hence a value might
not have the same string representation after any processing. That also
includes writing a floating point value in your script and directly
printing it without any mathematical operations.
Thank you for your interest in PHP.

Description:
------------
The following code should output exactly the same number in both echo
cases but it doesn't. However, multiply the number by 1000 instead of
the 100 on the first line and everything will work fine.
Reproduce code:
---------------
<?php
$test = (642 + 0.56) * 100;
echo $test . "\n";
$test = intval ($test);
echo $test;
?>
Expected result:
----------------
64256
64256
Actual result:
--------------
64256
64255
Very weird, I have only seen it happen with this particular case.
