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 Source : http://vosdroits.service-public.fr/professionnels-entreprises/F24271.xhtml ------------------------------------------------------------------------ [2014-05-03 18:21:28] kylekatarnls at gmail dot com Description: ------------ --- 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 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=67195&edit=1
