Description:
------------
The binary numbers format（see #50648, https://bugs.php.net/bug.php?id=50648)
was introduced to PHP 5.4.0alpha3.

However, its boundary value is wrong for judging whether return value shoud be integer or floating point number. See test script.

Test script:
---------------
<?php
var_dump(0b1111111);
var_dump(0b1111111111111111);


Expected result:
----------------
int(127)
int(65535)

Actual result:
--------------
int(127)
float(65535)

Fixed in SVN, but binary literals need to be mentioned at http://www.php.net/manual/en/language.types.integer.php

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.
