Do you simply want to format su
There is a DecimalFormat class generally available in Java. It can
handle the precision amongst other things (like separator character
based on locale, currency unit based on locale, etc.) while
string-representing doubles.
Here's the full API:

You could use String.format() of Formatter() with a ".2f" type format
(this one means: two digits in the fractional part).

You could also multiply the number by 100, or 10, as needed, convert it
to an integer thus
I have a calculator app and I want to round the number after comma.
Like, if the result is 15,3 I want to keep it on 15,33 or 15,3
Does any know how to do that?
Thanks, I really appreciate the help
