(2) The total number of digits that can be designated by
(3) The number of digits that can be designated by
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
2147483648 to 2147483647.
(5) After conversion, character string data is stored at the device number following
indicated below:
(a) The sign "20
(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",
"2E
