Rounding to decimal places

It can be done with custom code

DecimalFormat df = new DecimalFormet("#.#");
df.setRoundingMode(RoundingMode.HALF_UP);

YOURNUMBER = Double.parsDouble(df.format(YOURNUMBER));

You can always round using format text block

If you want to, you could also do the following:
[round(Value*100)]/100
For example [round(1.2345*100)]/100=1,23 → [round(123,45)]/100=1,23
