Bug description:Modulo is not accurate with double

Description:
------------
In C++ :

1290594600000 % 86400000 = 37800000 //correct

But In PHP :

1290594600000 % 86400000 = 30811200 //wrong



However, in PHP : 

1290594600000 - (floor(1290594600000/86400000)*86400000) = 37800000
//correct!



Can modulo opertor be implemented this way when left value > PHP_INT_MAX ?



See Patch in attachement

Test script:
---------------
echo 1290594600000 % 86400000;

echo "\n";

echo 1290594600000 - (floor(1290594600000/86400000)*86400000);

Expected result:
----------------
37800000

37800000

Actual result:
--------------
30811200

37800000
