If there is 16#20 or 16#30 between the sign character and the first value which is not 0 in the
string in S, 16#20 or 16#30 is ignored when the string is converted into the binary number.

If 16#2E, which represents the decimal point, is ignored, the string in S should be within the
range between -2147483648 and 2147483647. For example, if the string is “1234567.8”, users
have to check whether “12345678” is within the range.
4. If the sign code in S is 16#20, 16#2B, and 16#30 the conversion result is a positive value. If the
sign code in S is 16#2D, the conversion result is a negative value.
5. In the string in S, except for the sign code, the code representing the decimal point, and the
code which can be ignored, i.e. 16#20 or 16#30, the other codes have to be within the range
between 16#30 and 16#39.
