Converting INT to STRING

(Process)
These functions convert a value from INT data type to STRING data type.

Processing details
■Operation processing
• These functions convert the value input to (s) from INT data type to STRING data type, and output the converted value from
(d).
(s)
INT
• Input an INT data type value to (s).
• As sign data, 20H (space) is stored if the input value is positive, and 2DH (-) is stored if the value is negative.
• If the number of digits in the input value is less than the number of significant digits, 20H (space) is stored for the upper
digit(s).
Ex.
When the value -123 is input
(s)
-123
• When SM701 (Number of output characters selection) is off, 00H is stored at the end of the string (4th word).
