How can i count full rotations of object and then add point for each one

IEnumerator WaitForTouchRelease()
{
while(true)
{
if(Input.GetMouseButtonUp(0))
{
pos1 = MakeFormula(Input.mousePosition.y / Screen.height);

				dist = pos1 - pos0;

				break;
			}

			yield return 0;
		}

		m_rig.AddForce(Vector2.up * dist * forceMult);

		m_rig.AddTorque(rotateSpeed);

		PlaySoundBounce();

		yield return new WaitForSeconds(1);

		floorTouched = false;
	}

	public Text textPoint;

	int point = 0;

	void Add1Point()
	{
		point++;

		if(textPoint != null)
			textPoint.text = point.ToString();

		PlaySoundSuccess();
	}

	void OnCollisionEnter2D(Collision2D coll)
	{
		if(floorTouched)
			return;

		floorTouched = true;

		PlaySoundCollision();

		StartCoroutine(WaitForVelocityNull());
	}

	IEnumerator WaitForVelocityNull()
	{
		while(m_rig.velocity.y != 0)
		{
			yield return 0;
		}

		yield return new WaitForSeconds(0.5f);

		if(m_rig.transform.eulerAngles.z < 15)
		{
			m_rig.velocity = Vector2.zero;

			Add1Point();

			StartCoroutine(WaitForFirstTouch());
		}
		else if(m_rig.transform.eulerAngles.z > 359)
		{
			m_rig.velocity = Vector2.zero;

			Add1Point();

			StartCoroutine(WaitForFirstTouch());
		}
	
		else
		{
			textPoint.text = "Game Over";

			Util.SetLastScore(point);

			ShowAds();

			yield return new WaitForSeconds(0.2f);

			Util.ReloadLevel();
		}
	}
