• If 2BH(+) is specified for the sign or the sign is omitted in decimal point format, the converted single-precision real number
is treated as a positive value. If 2DH(-) is specified for the sign, it is treated as a negative value.
• If 20H (space) or 30H (0) exists between digits excluding the first 0 in the character string in the device specified by (s), the
instruction performs conversion by ignoring 20H and 30H.
■Exponential format
• When the character string in the device specified by (s) is in exponential format, conversion is performed as shown below.
• The character string in the device specified by (s) to be converted to a single-precision real number is converted by
assuming that the six digits excluding the sign, decimal point, and exponent are effective and the seventh and subsequent
digits are discarded.
