Bug description:money_format round error
Description:
------------
if you round with money_format, some small numbers with 0.005 are rounded
down instead of up.
Numbers bigger than 63.5 are all rounded falsly down like with floor()
Test script:
---------------
for($i=0;$i<70;$i++) {
echo($i.'.005 =>'.money_format('%.2i',$i+0.005).'<br>');
if($i<10)
echo($i.'.00500000000000001=>'.money_format('%.2i',$i+0.00500000000000001).'<br>');
}
Expected result:
----------------
0.005 =>0.01
0.00500000000000001=>0.01
1.005 =>1.01
1.00500000000000001=>1.01
