A convention for storing numerals, one per half-byte, with the final half-byte being an indicator of the sign. Common values for the sign are C (positive) D (negative) and F (unsigned, treated as positive)

A convention for storing numerals, one per half-byte, with the final half-byte being an indicator of the sign. Common values for the sign are C (positive) D (negative) and F (unsigned, treated as positive). Rare, but possible, other values for the sign are A (positive), B (negative) and E positive.
