Packed Decimal representation. Two digits are stored in each byte. Last nibble is for
sign. (F for unsigned positive, C for signed positive and D for signed negative)
Formula for Bytes: Integer ((n/2) + 1)) => n is number of 9s.

Answer / sunny kalra

Also, if you need more than 18 decimal digits, you must use COMP-3 (or DISPLAY) as COMP variables cannot exceed 18 digits while COMP-3 can be up to 31 digits.
