5) The ASCII code "2CH" (+) will be stored as the sign for the exponent portion of the
value if the exponent is positive in value, and the code "2D
H" ( ) will be stored if the
exponent is a negative value.
6) The exponent portion is fixed at 2 digits.
If the exponent portion is only 1 digit, the ASCII code "30
H" (0) will be stored
between the sign and the exponent portion of the number.
7) The value "00
H" is automatically stored at the end of the converted character string.
Operation Error
(1) In any of the following cases, an operation error occurs, the error flag (SM0) turns ON, and
an error code is stored into SD0.
