Description:
------------
the round() function doesn't give me the results described in the documentation example.


Reproduce code:
---------------
// from the documentation example

$foo = round( 3.4 );   // $foo == 3.0
var_dump($foo);

$foo = round( 3.5 );   // $foo == 4.0
var_dump($foo);

$foo = round( 3.6 );   // $foo == 4.0
var_dump($foo);


Expected result:
----------------
float(3) float(4) float(4)

(PHP Version 4.3.3RC1 version)

Actual result:
--------------
float(3) float(3) float(3)
