Bi-quinary coded decimal

Bi-quinary Coded Decimal (BQCD) is a numerical representation system that encodes decimal digits using a combination of binary and quinary (base-5) systems. It is primarily used in specific applications, such as early computing and programming, where there is a need for efficient representation of decimal numbers. Here's how BQCD works: 1. **Two Parts**: The code splits the representation of a decimal digit into two components.
