Or use '#' on the right to make the additional digits optional, as in with #.## (0.30) would drop the trailing 0 to become (0.3).If you want to print/write double value at console then use Or since you're working with currency, you could see how Formatter class is also a good option. then just recombine.Thanks for contributing an answer to Stack Overflow! For example in Spanish, the format would be "#,##". Where developers & technologists share private knowledge with coworkersProgramming & related technical career opportunities No solution that stores the result in floating-point can possibly work. Instead, use For two rounding digits. For example, double value is 3.72 and if I use format() function, new double value changes 3,72 and If I wanna set this new value to double property, it will be throwed exception of NumberFormatException: For input string: "3,72".
You need the second decimal place to show even if it's a zero. In fact String.format() might round like printf() does, but I'm not sure about that right now.

Additionally, say I have a double that gives me .5, i need it to read .50. for example:

Use Jonik's answer instead.this is wrong String.format("%.2f",$F{accrued_interest})Perfect answer, because result of value will be calculated with This doesn't actually do anything in a pass-by-value language like Java, let alone what the OP asked for.

In which case converting to a string and substring'ing it would work just as easily. (Im not talking here only about the value of Math.PI or Math.E, but about all double values that contain many decimal places) Basically I need to limit, NOT ROUND, to two decimal places. – RuudVanNistelrooy May 2 '14 at 5:54 your coworkers to find and share information.

You need the second decimal place to show even if it's a zero. In the above program, we've used DecimalFormat class to round a given number num.. We declare the format using the # patterns #.###.This means, we want num upto 3 decimal places. (33 answers)

See my answer in the duplicate for why.Should be the accepted answer because the accepted one is such messy compared to your clean and readable answerI need to round a double to use it as a granularity level in further calculations@odiszapc: Then you're using the wrong datatype. your coworkers to find and share information. So use String.format() method.

static BigDecimal valueOf (long val): This method translates a long value into a BigDecimal with a scale of zero. I think .format() will round the numbers using half-up, afaik?You could multiply it by 100 and then cast to an int (or taking the floor of the number), before dividing by 100 again.
