How to add floating bounce effect to sprite?

Question

I'm trying to add a floating bounce effect to one of my sprites but I don't know the best way to approach this and the way I'm trying(code below) isn't really working?

 #pragma strict
 
 public var gameObjectPos : Transform;
 
 function Update () {
 
     if (gameObjectPos.transform.position.y < 2) {
 
         gameObject.transform.position += Vector3.up * 0.02;
     
     }
     
     if (gameObjectPos.transform.position.y == 2) {
         
         gameObject.transform.position += Vector3.down * 0.02;
         Debug.Log("To High");
         
     }
 
 }

Here is an alternate:

 #pragma strict
 
 var floatSpan = 2.0;
 var speed  = 1.0;
 
 private var startY : float;
 
 function Start() {
     startY = transform.position.y;
 
 }
 
 function Update() {
      transform.position.y = startY + Mathf.Sin(Time.time * speed) * floatSpan / 2.0;
 }

It uses the start position as the midpoint of the bounce. 'floatSpan' is the height (bottom to top) of the bounce.
