Class DMoney

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Cloneable, java.lang.Comparable<java.math.BigDecimal>
    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!
