7 APPLICATION INSTRUCTIONS
7.8 String Processing Instructions
Processing details
• These instructions add a decimal point to the 16-bit binary data in the device specified by (s2) at the location specified by
(s1), convert the data to character string data, and store the converted data in the device areas specified by (d) and later.
Ex.
When converting data "-123" in (s2) into a string assuming that the number of decimal places is one ("-12.3")
• The total number of digits that can be specified by (s1) is 2 to 8.
• The number of digits in the decimal part that can be specified by (s1)+1 is 0 to 5. Note that the number of digits in the
decimal part must be smaller than the total number of digits minus 3.
