Description:
------------
Why is (int) conversion ignoring hexadecimals if all other operation using integer conversions convert them?
I think (int) conversion should also convert hexadecimals to be consistent with others.

Reproduce code:
---------------
$a = "0x10";

var_dump((int)$a,$a * 1,$a == "16");

Expected result:
----------------
int(16)
int(16)
int(17)
bool(true)

Actual result:
--------------
int(0)
int(16)
int(17)
bool(true)
