• As the number of significant figures of string type data is 6, the 7th and later digits excluding the sign, decimal point, and
exponent part are cut and converted.

• When a sign is not specified or '2BH' (+) is specified for a sign in decimal form, string type data is converted as a positive
value. When '2DH' (-) is specified for a sign, string type data is converted as a negative value.
• When a sign is not specified or '2BH' (+) is specified for a sign of the exponent part in exponential form, string type data is
converted as a positive value. When '2DH' (-) is specified for a sign of the exponential part, string type data is converted as
a negative value.
