Python to_twos_comp Examples

Example #1

     bin_len = self.length.decode_lengths(message)[0] * 8
     min = pow(-2, (bin_len - 1))
     max = pow(2, (bin_len - 1)) - 1
     if not min <= to_int(value) <= max:
         raise AssertionError('Value %s out of range (%d..%d)' %
                              (value, min, max))
     return to_twos_comp(value, bin_len)
