Description:
------------
I know about "unpredictable" issues with floatingpoint calculations, but this one is quite funny:

...
echo intval(100*(27/100));
//output: 27
echo intval(100*(28/100));
//output: 28
echo intval(100*(29/100));
//output: 28
echo intval(100*(30/100));
//output: 30
echo intval(100*(31/100));
//output: 31
...


Reproduce code:
---------------
echo intval(100*(29/100));


Expected result:
----------------
29

Actual result:
--------------
28

Might be funny... but it's still the same problem.
