public class DMoney
extends BMoney

A DMoney is the same as a BMoney but will be treated differently when stored in the database.
A BMoney is stored as a DOUBLE for the value and an INTEGER for the scale. A DMoney is stored as a DECIMAL for the value and an INTEGER for the scale. The DECIMAL is stored with scale 0!
