Using arithmetic

If the programming language does not support bit operations, perform the following steps using integer arithmetic:

  1. Select one of the following values, according to the type of encoding required:

    • 1 for the binary integer encoding

    • 16 for the packed decimal integer encoding

    • 256 for the floating point encoding

    Call the value

    A.

  2. Divide the value of the Encoding field by A; call the result

    B.

  3. Divide

    B by 16; call the result C.

  4. Multiply

    C by 16 and subtract from B; call the result D.

  5. Multiply

    D by A; call the result E.

  6. E is the encoding required, and can be tested for equality with each of the values that is valid for that type of encoding.
