Bug description:  Problem when comparing casted strings

Description:
------------
I'm casting a string to a double; afterwards the casted result does differ
from the original string, but comparing them does not work properly and
leads to a wrong bool.

strcmp works, though.

Reproduce code:
---------------
<?php

$stringAmount = '2008-06-13 14:24:00';

$doubleAmount = (double) $stringAmount;

echo 'doubleAmount: ' . $doubleAmount . ' stringAmount: ' . 
$stringAmount;

if ($doubleAmount != $stringAmount)
{
    echo '<br/>' . $doubleAmount . ' is not equal to' . $stringAmount;
}
else
{
    echo "<br/> both are equal";
}

?>

Expected result:
----------------
doubleAmount: 2008 stringAmount: 2008-06-13 14:24:00
2008 is not equal to2008-06-13 14:24:00

Actual result:
--------------
doubleAmount: 2008 stringAmount: 2008-06-13 14:24:00
both are equal
