There's some freaky math going on there or something. I added a couple
of other echos in to see and for some reason it seems to be losing
single digit value (subtracting, rounding down, I don't know).
$calculatedGross = $originalNet + ( $originalNet * $commissionPct * 0.01 );
echo ( "Gross : " . (int)$calculatedGross ." = ". $originalNet ." + ( ".
$originalNet ." * ". $commissionPct ." *.01 )<br />\n" );
$calculatedNet = $calculatedGross / ( 1 + ( $commissionPct * 0.01 ));
echo ( "Net : " . (int)$calculatedNet." = " . (int)$calculatedGross . "
/ ( 1 + ( " . $commissionPct . " * .01 ) )<br />\n" );
