return new DecimalFormat().format(no) + countEnding(no);

return createDecimalFormat(pattern, '.');

DecimalFormat CreateDecimalFormat(int numberOfDecimalsDisplayed)
Gets the amount of decimals that should be displayed with a DecimalFormat object.

if (numberOfDecimalsDisplayed < 1)
 return new DecimalFormat("#");
String format = "#.";
for (int i = 1; i <= numberOfDecimalsDisplayed; i++)
 format += "#";
return new DecimalFormat(format);

DecimalFormat createDecimalFormat(String pattern)
create Decimal Format

return new DecimalFormat(pattern);

DecimalFormat createDecimalFormatter(String pattern)
create Decimal Formatter

DecimalFormat formatter = (DecimalFormat) NumberFormat.getCurrencyInstance(Locale.US);
formatter.applyPattern(pattern);
return formatter;

NumberFormat createNumberFormat()
create Number Format

DecimalFormat result = new DecimalFormat();
result.setMaximumFractionDigits(4);
return result;

NumberFormat createNumberFormat(int cnt)
create Number Format

StringBuilder sb = new StringBuilder();
sb.append("0");
if (cnt > 0) {
 sb.append(".");
 for (int i = 0; i < cnt; i++) {
 sb.append("0");
return new DecimalFormat(new String(sb));

NumberFormat createOrderVolumeNumberFormat()

format.setMinimumFractionDigits(0);
format.setMaximumFractionDigits(14);
return format;

String expFormatRupiah(Number input, boolean prependRp)
exp Format Rupiah

if (rupiahFormat == null) {
 DecimalFormatSymbols decimalFormatSymbols = new DecimalFormatSymbols();
 decimalFormatSymbols.setCurrencySymbol(prependRp ? "Rp " : "");
 decimalFormatSymbols.setMonetaryDecimalSeparator(',');
 decimalFormatSymbols.setGroupingSeparator('.');
 rupiahFormat = (DecimalFormat) NumberFormat.getCurrencyInstance();
 rupiahFormat.setDecimalFormatSymbols(decimalFormatSymbols);
return rupiahFormat.format(input);
