Processing details
■Operation processing
• INT_TO_STR, INT_TO_STR_E
Converts word (signed) type data input to (s) into string type data, and outputs the operation result from (d).
s
Word (signed) type
When SM701 (signal for switching the number of output characters) is OFF,
"00 " is stored.
H
'20H (space)' is stored in 'Sign data' when the input value is positive; '2DH (-)' is stored when negative.
If the number of significant figures is less, '20H (space)' is stored to high-order digits.
Ex.
Inputting -123
s
-123
Word (signed) type
When SM701 (signal for switching the number of output characters) is OFF, "00H" is stored to the end of the character string.
