Parse Errors from different Locales '.' "," in Line 188 on wattage calculation.. I Fix it Allround for me: Locale myLocale =Locale.getDefault(); //Locale.GERMAN; NumberFormat f = NumberFormat.getInstance(myLocale); DecimalFormat twoDForm = new DecimalFormat("#.##"); Double myNumber=((current / 1000) * voltage); try { twoDForm.parse(twoDForm.format(myNumber)); } catch (ParseException e) { // TODO Automatisch generierter Erfassungsblock e.printStackTrace(); } Double wattage = Double.valueOf(myNumber);

Interesting, I hadn't thought of locale being an issue. Looks like this would fix it for everyone not in the US. Can you submit this as a pull request and I can merge it.

Thanks.

  1. Updatet Numberformat Locales
  2. Try&Catch Block for aftereffects on Double Parsing
  3. Forgotten Imports
