- When the number of digits of the decimal part is set to any value other than "0", "2EH (.)" is
automatically stored in "specified number of digits of decimal part + 1"th digit.
When the number of digits of the decimal part is "0", "2EH (.)" is not stored.

- When the total number of digits subtracted by the digits for sign, decimal point and decimal part is larger
than the integer part of the binary floating point data, "20H (space)" is stored between the sign and the
integer part.
