2) Set the number of all digits
3) Set the number of digits of the decimal part
Make sure to satisfy "Number of digits of decimal part <= (Number of all digits -3)".
4) 16-bit binary data to be converted stored in
5) Converted character string data is stored in
- As the sign, "space" (20H) is stored when the 16-bit binary data stored in
