There is actually a much easier and simpler way to chop off any fraction of a penny in financial
calculations. Here is the code:
function round_down_to_penny( $p ) {
$p=round($p-0.005,2);
return $p;
}
In other words, just subtract 0.005 and round that to 2 decimal places.
You can easily verify that any price from say 7.21 to 7.2199999 ends up as 7.21.
