 Densely packed decimal

Densely Packed Decimal (DPD) is a method of encoding decimal numbers in a way that optimizes storage and processing efficiency, particularly in environments where both decimal precision and performance are important, such as financial applications. In standard decimal representation, each digit is typically stored separately (for instance, in ASCII or binary-coded decimal (BCD) format), which can lead to inefficient use of storage space. DPD compresses the representation of decimal digits by packing them more efficiently.
