Description:
------------
If string contains hexadecimal number, such as '0x05' it correctly explicitly 
casts to integer(resulting zero):
php > var_dump((int) '0x05');
int(0)
but incorrectly casts implicitly (resulting its value, 5)
php > var_dump(1 * '0x05');
int(5)

Same for floats:

php > var_dump((float) '0xffffffffff');
float(0)
php > var_dump(1 * '0xffffffffff');
float(1099511627775)

P.S.: Tests were made on x86 (i686) Linux machine.


Test script:
---------------
<?php
var_dump(1 * '0x05');
var_dump(1 * '0xffffffffff');




Expected result:
----------------
int(0)
float(0)

Actual result:
--------------
int(5)
float(1099511627775)
