decimali in JSP

[lanc71]

Qualcuno riesce a spiegarmi perché in questo codice mi vengono azzerati i decimali delle spese di spedizione? In questo modo il totale è diverso da quello effettuato.

• DecimalFormat df = new DecimalFormat("#,###.00");
  double ss = 0.00;
  
  <script language="javascript">
  function checkOrdine(){
  ok = true;
  if (ok && document.getElementById("conto").checked == false && document.getElementById("contrassegno").checked == false && document.getElementById("carta").checked == false && document.getElementById("ritiro").checked == false) { alert("Impossibile ordinare senza scegliere il tipo di pagamento.");ok =false;}
