using Quaternion.lookrotation

Hey guys I’m trying to use Quaternion.lookrotation to get an object to rotate towards a target, it then moves in the forward direction, however it is returning bizarre results. I’ll post the code and some example figures:

//movement direction
		Vector3 dir = position - myTransform.position;

		Debug.Log ("Dir: " + dir);
		// Rotate towards the target
		myTransform.rotation = Quaternion.Slerp(myTransform.rotation,
		                                        Quaternion.LookRotation(dir), rotationSpeed * Time.deltaTime);

		Debug.Log ("target rotation: " +Quaternion.LookRotation(dir));
		Debug.Log ("mytransform.rotation: " + myTransform.rotation);

ok so here lies my confusion. In a test run i did, the vector3 Dir came out as
(0.5, 0.0, 0.0)… then using quaternion lookrotation(dir) comes out as (0.0, 0.7, 0.0, 0.7)… I can’t even begin to understand where it got that from? As always any help is greatly appreciated.

Any mod please close this question as it has become irrelevant.
