Noob rotation help

Unity Engine
1 
float angle=-45;
Quaternion startRot=myobj.transform.rotation;   //i take this at start only
myobj.transform.rotation= startRot*Quaternion.Euler(0,0,angle); //on update

why It won’t rotate with negative values?
inside the editor I can put whatever value I want on the z…

EDIT: nevermind…my fault!

2 
var angle : float=45;

function Update () {
	var s=transform.rotation;
	var q=Quaternion.Euler(0,0,angle);
	transform.rotation=Quaternion.Slerp(s, q, 0.01); //on update
}

Perhaps your misusing the Quaternions. :wink:
