Need Help With Decimalformat Showing too many/not enough decimals

Right now I have this:

DecimalFormat form = new DecimalFormat("0.00");form.toPattern();form.format(tot);

The Java API said that 0 would be a digit that you didn't want ignored (ie an extra zero), but it's only showing the first 0 after the decimal. This is a monetary value so I have to have exactly 2. Also sometimes it weirds out and goes from 0.05 to 0.0600...002 or from 0.09 to 0.0999..., so I need it to round to those 2 decimals, too.

As for the DecimalFormat I've tried "#.##", "0.#0", "#.#0", and "0.##" but those didn't work, either.

hi beeseven,Your code seems fine. I tried it out and the results came as expected i.e, with 2 decimal places(either rounded of if more decimal places exist or 0 appended if decimal places not sufficient).you also do not need to call form.toPattern() method. but that does not make a difference anyway.what is the data type of 'tot' that you are passing to format() method. That might be affecting the output. btw fyi I tried it out on JDK 1.4.2, if the issue is still not solved, could you post more of the code.Also check out if you are using the DecimalFormat class from the java.text package only. It might be the a class with the same name existing in some other package in your classpath has been accidentally imported. This happens in case you are using IDE and you have chosen the import from a drop down or something automatically.Cheers.

I got some help with it in my class: DecimalFormat returns a string but doesn't change the variable, so I had to say

label.setText("$"+form.format(tot));
