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).
5)
stores 16-bit binary data converted from a character string with the decimal point ignored.
In the character string located after
, "space" (20H) or "0" (30H) put between the sign and the first
number except "0" is ignored in conversion into 16-bit binary data.
