Unfortunately, ranzoategui's (and my revision) round version did not work well (try to round
8.075 to 2 decimals for example).
I found out the best way to achieve a good round is to add a tiny number to the value before
rounding. This seems to work fine in all cases (and luckily it's faster than previous methods):
<?
function stdround($num, $d=0)
{
return round($num + 0.0001 / pow(10, $d), $d);
}
?>
