7
• With regard to character string, six digits excluding the sign, decimal point and exponent part are valid, and the 7th and later
digits are discarded during conversion.
• When 2BH (+) is specified as the sign in the floating point format or when the sign is omitted, a character string is converted
into a positive value. It is handled as negative value during conversion when the sign is set to 2DH (-).
• When 20H (space) or 30H (0) exists between numbers except the first 0 in a character string specified by (s), 20H or 30H is
ignored during conversion.
■Exponent format
• When the character string specified by (s) is in exponent format, the operation is executed as follows.
• With regard to character string, six digits excluding the sign, decimal point and exponent part are valid, and the 7th and later
digits are discarded during conversion.
