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()?

stripTrailingZeros() is an inbuilt method in Java that returns a BigDecimal which is numerically equal to this one but with any trailing zeros removed from the representation. So basically the function trims off the trailing zero from the BigDecimal value.
format("%. 2f", 1.23456); This will format the floating point number 1.23456 up-to 2 decimal places, because we have used two after decimal point in formatting instruction %.
String truncated = String. valueOf((int) doubleValue); We can confidently use this approach when we're guaranteed that the double value is within the range of an int.
You can use setScale() to reduce the number of fractional digits to zero. Assuming value holds the value to be rounded: BigDecimal scaled = value. setScale(0, RoundingMode.
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); new DecimalFormat("#0.##").format(bd) If you love us?
