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).
• 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.
Operation error
There is no operation error.
Value of (s) Data of (d) to (d)+2 Value of (s) Data of (d) to (d)+2
• 0
• Positive value (1
digit in numeric
part)
• The upper byte of (d) is filled with 00H.
• (d)+1 and later remain unchanged. • Positive value (2
digits in numeric
part)
• Negative value (1
digit in numeric
part)
• (d)+1 is filled with 00H.
• (d)+2 and later remain unchanged.

• Positive value (9
digits in numeric
part)
• Negative value (8
digits in numeric
part)
• The upper byte of (d)+4 is filled with 00H.
• (d)+5 and later remain unchanged. • Positive value (10
digits in numeric
part)
• Negative value (9
digits in numeric
part)
• (d)+5 is filled with 00H.
• Negative value (10
digits in numeric
part)
• 00H is stored in the upper byte (1) of (d)+5 when
SM701 (Number of output characters selection) is
off, and 20H (space) is stored when it is on.
