Here is a simplifie version of my code :
<?php
$total = 0;
$ht = 10.03;
$vat = 19.6;
$total += $ht*($vat/100+1);
print("Total = ".sprintf("%0.2f", $total));
$total += $ht*($vat/100+1);
print(" - Total 2 = ".sprintf("%0.2f", $total));
?>
I get 12.00 and 23.99 ... what should I do to get 12.00 and 24.00 ?

Hello, I'm trying to write a invoice script but I have encountered a
slight problem.
Each product needs to be listed without tax, and at the end of the
file I need to show the VAT. In France VAT is 19.6%
So €10.03 without vat = €12.00 with vat.
So I do this :
$totalwithoutvat = 0;
$totalwithoutvat = 0;
$totalvat =0;
while ( $itemwithoutvat) = each( $px ) )
{
$totalwithoutvat += $itemwithoutvat;
$totalwithoutvat += sprintf("%0.2f", $itemwithoutvat * ( 1 + 19.6/100 ));
$totalvat += sprintf("%0.2f",$itemwithoutvat * 19.6/100);
}
print ("Total Vat =".sprintf("%0.2f",$totalvat)." - Total without vat
= ".sprintf("%0.2f",$totalwithoutvat)." - Total with vat =
".sprintf("%0.2f",$totalwithvat));
But I'm not sure I am using sprintf correctly, maybe I should use a
different function because :
When I have one item at 10.03, the result is : Total Vat = 1.97 -
Total without vat = 10.03 Total with vat = 12.00
but if I have two items at 10.03 the result is : Total vat = 3.93 -
Total without vat = 20.06 Total with vat = 23.99
but I need it to be : Total vat = 3.94 - Total without vat = 20.06
Total with vat = 24.00
So from what I can see, sprintf only seems to work for printing and
the actual result is kept in memory, is this correct ? if so what
function should I use instead?
Thanks in advance :)
