2) The numeric range of data stored in
3) As "sign data" (low-order byte of
and "2DH (-)" is set when the data to be converted is negative.
4) An ASCII code for each digit is within the range from 30H to 39H.
5) When an ASCII code for each digit is "20H (space)" or "00H (null)", it is handled as "30H".
