        byte[] positiveBytes = positiveValue.ToByteArray();
        byte[] negativeBytes = negativeValue.ToByteArray();
        // Instantiate new BigInteger from negativeBytes array.
        Console.Write("Converted {0:N0} to the byte array ", negativeValue);
        foreach (byte byteValue in negativeBytes)
           Console.Write("{0:X2} ", byteValue);

        negativeValue2 = new BigInteger(negativeBytes);
        Console.WriteLine("Converted the byte array to {0:N0}", negativeValue2);
