        // now let's create some longer numbers
        vector = new Vector3(1.0f / 3.0f, -Mathf.PI, Mathf.Exp(-2.0f));

        // we get (0.333333, -3.141593, 0.135335)
        Debug.Log("fractional part is 6: " + vector.ToString("F6"));

        // note how F8 cannot display these numbers as we want
        // (0.33333330, -3.14159300, 0.13533530)
        Debug.Log("fractional part is 8: " + vector.ToString("F8"));
