Quaternion Slerp - Rotate to Angle?

Okay, here’s the code from the reference manual:

 // Interpolates rotation between the rotations
 // of from and to.
 // (Choose from and to not to be the same as
 // the object you attach this script to)
 
 var from : Transform;
 var to : Transform;
 var speed = 0.1;
 function Update () {
      transform.rotation =
      Quaternion.Slerp (from.rotation, to.rotation, Time.time * speed);
 }

My question is, can I use Quaternion.Slerp to rotate to angles given in floats, rather than rotating towards external objects?

Cheers!

Yes by itself is too short an answer
