How can i test if a GetAxis is not pressed?

How can i test if a GetAxis from a controller input is not pressed?

If this is for touch device, this issue will be useful:

Is there a Way to transform GetAxis into Android Touch?

I think this will help

	void Update ()
    {
        if (Input.GetAxis("Vertical") == 0 && Input.GetAxis("Horizontal") == 0)
        {
            Debug.Log("Nothing pressed");
        }
    }
