Bug description:  Wrong result from round()

Description:
------------
I have some troubles with following round() function.
I think the operation +1 produces the problem.




Reproduce code:
---------------
var_dump(round(65536.335,2));
var_dump(round(65535.335 + 1,2));


Expected result:
----------------
float(65536.34)
float(65536.34)


Actual result:
--------------
float(65536.34)
float(65536.33)
