- When the number of all digits stored in
excluding the sign and decimal
point is larger than the number of digits
of 16-bit binary data stored in ,
"space" (20H) is stored in each digit
between the sign and the numeric
value.
When the number of all digits stored in excluding the sign and decimal point is smaller than the
number of digits of 16-bit binary data stored in , an error is caused.
- "00H" indicating the end of a character string is automatically stored at the end of a converted character
string.
When the number of all digits is even, "0000H" is stored in the device after the last character.
When the number of all digits is odd, "00H" is stored in the high-order byte (8 bits) of the device storing
the final character.
2. 32-bit operation (DSTR and DSTRP)
1) All digits (specified by ) of 32-bit binary data stored in [ +1, ] are converted into ASCII
codes 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 and later.
2) Set the number of all digits in the range from 2 to 13.
3) Set the number of digits of the decimal part +1 in the range from 0 to 10.
Make sure to satisfy "Number of digits of decimal part <= (Number of all digits -3)".
4) 32-bit binary data to be converted stored in [ +1, ] should be within the range from -
2,147,483,648 to +2,147,483,647.
