Format a BigDecimal as String with max 2 decimal digits removing 0 on decimal part

Question

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

I used DecimalFormat for formatting the BigDecimal instead of formatting the String, seems no problems with it.

The code is something like this:

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

DecimalFormat df = new DecimalFormat();

df.setMaximumFractionDigits(2);

df.setMinimumFractionDigits(0);

df.setGroupingUsed(false);

String result = df.format(bd);
