Rounding Function Query

Question

Hi All, Currently I would like to round off to 2 Decimal for a double value.
Below is my code:
DecimalFormat df = new DecimalFormat("#0.00");
String result = df.format(1.345);
However, the result turn out to be "1.34" instead of "1.35". If the double value is "1.3451", the result is "1.35". For the other input value, the rounding works fine. Hence, can anyone out there know why there is such a behaviour and how I can resolve this issue? Really appreciate if someone can response to my query.
Thank you.

Answer 1

But 1.5 is rounded to 2 with that code...... that code referring to
DecimalFormat df = new DecimalFormat("#0");
String result = df.format(1.5);Where was this code posted besides here?
Any obvious
reason why?DecimalFormat seems to round using BigDecimal.ROUND_HALF_EVEN
You are rounding to the nearest int, so that is either 1 or 2, since 1.5 is exactly between those numbers, it picks the even number, 2.
I think there was a request to change this to round the way people normally think to round.
:) Is this good timing or what?
