From manual page: http://www.php.net/functions.anonymous

Le calcul suivant est faux :
$total += ($pricePerItem * $quantity) * ($tax + 1.0);

HC => TTC
10000 * (1+0.055) => 10550
TTC => HT
10550 * (1-0.055) => 9969,75 (faux devrait faire 10000)


Pour ajouter la TVA se calcul, il faut faire :
$total += ($pricePerItem * $quantity) / (1.0 - $tax);

HC => TTC
10000 / (1-0.055) => 10582,011
TTC => HT
10582,011 * (1-0.055) => 10000

Faux, le calcul est bon.

Le calcul TTC => HT s'effectue via la formule suivante :

TTC * (100/(TVA+100)) = HT

Soit pour notre exemple (10550 avec une TVA à 5.5) 
10550 * (100/(5.5+100)) = 10000
