public static UnsignedInteger valueOf(String s, int radix) {
        return valueOf(Integer.parseUnsignedInt(s, radix));
    }
Returns a {@code UnsignedInteger} object holding the value
extracted from the specified {@code String} when parsed
with the radix given by the second argument.

@param s     the {@code String} containing the unsigned integer
             representation to be parsed
@param radix the radix to be used while parsing {@code s}
@return the unsigned {@code long} represented by the string
        argument in the specified radix
@throws NumberFormatException if the {@code String} does not contain a
                              parsable {@code int}
