6.6 Data Conversion Instructions
■
Setting method of (s) for when SM705 (Number of conversion digits selection) is on
Set decimal ASCII data with a desired number of digits (including 00H (NULL code)) in (s). Note that 00H (NULL code) is not
required to be set if the integral part has the maximum number of digits (5 digits).
The following table lists the setting method of (s).
• The ASCII data in the device specified by (s) to (s)+2 is within the range from -32768 to 32767 for the DABIN(P) instruction,
and it is within the range from 0 to 65535 for the DABIN(P)_U instruction.
• Set 2DH (-) to lower byte of (s)+0 as sign data when the ASCII data is negative. Set an ASCII code of the uppermost digit
instead of setting sign data when the ASCII data is 0 or positive.
• A value from 30H to 39H can be set in each place of ASCII code.
• If the value is positive and the numeric part has 5 digits, the data of the upper byte of (s)+2 or later is ignored. If the value is
negative and the numeric part has 5 digits, the data of (s)+3 or later is ignored.
• If a value 20H is set in each place of ASCII code, the value is processed as 30H. If a value 00H is set, the value is
processed as the end of the decimal ASCII data.
• In the following cases, 0 is stored.
Operation error
*1 When SM705 (Number of conversion digits selection) is off, no error is detected no matter what value is set for the ASCII code of the
first character.

• Positive value (1

• Set 00H in the upper byte of (s).
• The data of (s)+1 or later is ignored.
• Positive value (2
digits in numeric
part)
• Negative value (1
digit in numeric
part)
• Set 00H in the lower byte of (s)+1.
• The data of the upper byte of (s)+1 or later is
ignored.
• Negative value (4
digits in numeric
part)
• Set 00H in the upper byte of (s)+2.
• Positive value (5
digits in numeric
part)
• The data of the upper byte of (s)+2 or later is
ignored. Since the number of digits is the
maximum, 00H is not required to be set.
• Negative value (5
digits in numeric
part)
• The data of (s)+3 or later is ignored. Since the
number of digits is the maximum, 00H is not
required to be set.

• The first character is 00H (NULL).
• The first character is 2DH (-) and the second character is 00H (NULL).
Error code
(SD0)
Description
3401H
Invalid data that cannot be converted are input in (s) to (s)+2.
• The ASCII code of the first character is other than 2DH, 30H to 39H, 20H, and 00H.
• The ASCII code of the second character or later is other than 30H to 39H, 20H, and 00H.
• When the DABIN(P) instruction is used, ASCII data is out of the range from -32768 to 32767.
• When the DABIN(P)_U instruction is used, ASCII data is out of the range from 0 to 65535.
