Function and operation explanation
1. 16-bit operation (STR/STRP)
1) All digits (specified by ) of 16-bit binary data of the device specified by are converted into
character string while the decimal point is added to the position specified by the device storing the
number of digits of the decimal part ( + 1), and stored in the device specified by and later.
2) Set the number of all digits in the range from 2 to 8.
3) Set the number of digits of the decimal part + 1 in the range from 0 to 5.
Be sure to satisfy "(number of digits of decimal part) ≤ (number of all digits - 3)".
4) 16-bit binary data to be converted stored in should be within the range from -32768 to 32767.
