[java] Format a BigDecimal as String with max 2 decimal digits, removing 0 on decimal part

I have a BigDecimal number and i consider only 2 decimal places of it so i truncate it using:

bd = bd.setScale(2, BigDecimal.ROUND_DOWN)

Now I want to print it as String but removing the decimal part if it is 0, for example:

1.00 -> 1

1.50 -> 1.5

1.99 -> 1.99

I tried using a Formatter, formatter.format but i always get the 2 decimal digits.

How can I do this? Maybe working on the string from bd.toPlainString()?

Use stripTrailingZeros().

This article should help you.

The below code may help you.

protected String getLocalizedBigDecimalValue(BigDecimal input, Locale locale) {
    final NumberFormat numberFormat = NumberFormat.getNumberInstance(locale);
    numberFormat.setGroupingUsed(true);
    numberFormat.setMaximumFractionDigits(2);
    numberFormat.setMinimumFractionDigits(2);
    return numberFormat.format(input);
}

If its money use:

NumberFormat.getNumberInstance(java.util.Locale.US).format(bd)

new DecimalFormat("#0.##").format(bd)
