i have this code
that produces this output
Labor Amt: 96.25
PArts total: 109.08
Pay Total: 205.33
why is simple 2 decimal place math generating an answer of 0.0000000000002 ?
Code:
if ($debug) {
echo "Labor Amt: $lbrAmt<br> PArts total: $pTotal <br> Pay Total: $payTotal<br>\r\n";
}
$invBal = ($lbrAmt + $pTotal) - $payTotal;
?>
<table><tr><th>Labor: </th><td><?=$lbrAmt?></td></tr>
<tr><th>Parts:</th><td><?=$pTotal?></td></tr>
<tr><th>Payments:</th><td><?=$payTotal?></td></tr>
<tr><th>Balance:</th><td><?=$invBal?></td></tr></table>that produces this output
Labor Amt: 96.25
PArts total: 109.08
Pay Total: 205.33
