DSTR
(1) Adds a decimal point to the BIN 32-bit data designated by at the location designated by
, converts the data to character string data, and stores it following the device number
designated by .
(2) The total number of digits that can be designated by is from 2 to 13.
(3) The number of digits that can be designated by +1 as a part of the decimal fraction is from
0 to 10.
However, the number of digits following the decimal point must be smaller than or equal to
the total number of digits minus 3.
(4) The BIN data that can be designated by and +1 is within the range of from
2147483648 to 2147483647.
(5) After conversion, character string data is stored at the device number following as
indicated below:
(a) The sign "20H" (space) will be stored if the BIN data is positive, and the sign "2DH"
(minus sign) will be stored if it is negative.
(b) If the setting for the number of digits after the decimal fraction is anything other than "0",
"2EH" (.) will automatically be stored at the position before the first of the specified
number of digits.
If the number of digits in the decimal fraction part of the number is "0", the ASCII code
"2EH" (.) will not be stored.
