■Operation of when SM705 (Number of conversion digits selection) is on
Decimal ASCII data is stored right-justified in (d).
The following figures show an example of a value of (s) and a value stored in (d).
Value of (s) Data of (d) to (d)+2

• When the number of operation digits is less than the maximum number of digits (a sign + 10 digits), 00H is stored in the end
of the string regardless of the status (on/off) of SM701 (Number of output characters selection). If the end of the string is the
lower byte, 00H is also stored in the upper byte.
• When the number of operation digits is equal to the maximum number of digits (a sign + 10 digits), 00H is stored in the
upper byte of (d)+5 if SM701 is off. 20H (space) is stored in the upper byte of (d)+5 if SM701 is on.
