Question

Answer 1

You can specify the number of fraction digit after the decimal point, and/or the numbers before the decimal point. Of-course, setting the current locale is also important.

   private String formatNumber(double number) {

    NumberFormat nf = NumberFormat.getNumberInstance(Locale.getDefault());
    if (nf instanceof DecimalFormat) {
        try {
            DecimalFormat formatter = (DecimalFormat) nf;
            formatter.setDecimalSeparatorAlwaysShown(true);
            formatter.setMinimumFractionDigits(2);
            formatter.setMaximumFractionDigits(2);
            return formatter.format(new BigDecimal(number);
        } catch (NumberFormatException nfe) {
            nfe.printStackTrace();
        }
    }
    return null;
}
