Not an answer to your question, but you really need to know the following:

Never never never ever ever ever *ever* use binary floating point to do calculations with money. Use BigInteger instead.


The mind is a strange and wonderful thing. I'm not sure that it will ever be able to figure itself out, everything else, maybe. From the atom to the universe, everything, except itself.

There is something in the Java™ Tutorials; go through "Numbers" and note particularly the links to java.util.Formatter.
 
It is sorta covered in the JavaRanch Style Guide.
