u can use NumberFormat, which is in java.text.... something like this:

NumberFormat nf = NumberFormat.getNumberInstance();
or you can do it by hand  :)

double l = 3248.298475;
l = ((double)((int)(l * 100))) / 100;
.. Or you can use DecimalFormat, which is an extension of NumberFormat.

You can find it from java.text.DecimalFormat.

You can define a pattern according to which the formatting takes place. As in your question, to always format to two decimal (and a zero before decimal separator) even if there is only one (for ex. 123.5 -> 123.50) do this:

DecimalFormat df = new DecimalFormat("0.00");
double d = 12345.56789;
