2. 32-bit operation (DVAL and DVALP)
1) A character string stored in
and later is converted into 32-bit binary data. The number of all digits of the
binary data acquired for conversion is stored in
, the number of digits of the decimal part is stored in
+1, and the binary data is stored in [
+1,
].
In conversion from a character string into binary data, the data from
to a device number storing "00H" is
handled as a character string in byte units.
For example, when a character string "-12345.678" is specified in
and later, the conversion result is stored
in
and
as shown below.
2) Character string to be converted
a) Number of characters of character string and the numeric range when the decimal point is ignored
b) Character types used in characters to be converted
3)
stores the number of all digits. The number of all digits indicates the number of all characters (including the
number, sign and decimal point).
4)
+1 stores the number of digits of the decimal part. The number of digits of the decimal part indicates the
number of all characters after the decimal point "." (2EH).
Description
Number of all characters (digits)
2 to 13
Number of characters (digits) of decimal part
0 to 10 and smaller than "number of all digits
−3"
Numeric range when decimal point is ignored
−2,147,483,648 to +2,147,483,647
Example: 12345.678
Example: 12345.678
→ "12345678"
