 New Comment:

Note: I assume this is because log() returns a floating point value.
I.e. it's a precision issue?

Description:
------------
When performing a log(), and immediately type casting afterwards, the
value changes.

Test script:
---------------
<?php
$val = 1000;
echo log($val, 10) .' == '. (int) log($val, 10);
?>

Expected result:
----------------
3 == 3

Actual result:
--------------
3 == 2
