d) 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.
e) "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 last character.
2. 32-bit operation (DSTR/DSTRP)
1) All digits (specified by ) of 32-bit binary data stored in the device specified by 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 the device specified by 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.
Be sure to satisfy "(Number of digits of decimal part) ≤ (Number of all digits - 3)".
4) 32-bit binary data to be converted stored in should be within the range from -2,147,483,648 to
+2,147,483,647.
