Description:
------------
/* I would like to know if this 
is a bug, cuz i konw of some 
issues of defective processors
like my pentium II processor
I don't think that, cuz in 
the calculator of WinME the
Answer is Right (23+23/2=23)
This also happens with JavaScript... :-| :D

Reproduce code:
---------------
<?php
function Mm($a,$b){
$R=$a+$b*0.5;// Is The Same If I Put " /2 " Instead.
return $R;
}
echo Mm(23,23)."<BR>";//The Correct Would Be 23 Instead of 34.5
echo Mm(243,456)."<BR>";//'''''''''''''''''' 349.5 Instead of 471.
?>

Expected result:
----------------
To write the Correct Answers..

Actual result:
--------------
Doesn't givethe right Answer, and, it seems so stupid :D.. with all the respect :P, cuz 23+23=46, but, javascript do the same too, is an error on my processor or not?, the calc.exe shows the right answer.. :D... That bugs are from year 2000 xD.. :D
