Help can't get positive/negative value from angle :)

Well i have my player GameObject and camera GameObject
now i calculate the distance between them

Code (JavaScript):

1.  
2. var rotationObject : GameObject;
3. var player :GameObject;
4. var angle : float;
5. function PlayerRotation(){
6.    angle = player.transform.eulerAngles.y - rotationObject.transform.eulerAngles.y;
7.  
8. }

ok what i want to know now is the direction Negative and Positive
Example : instead of a value from 0-360 i want :
positive 0-180 negative 0-180
Concept Example :
i need the values for the Animator to know which direction to turn
when value +50 max Animation Is idle_RightTurn45°
when value +15 max Animation Is Idle
when value -15 max Animation Is Idle
when value -50 max Animation Is idle_LeftTurn45°
hope you understand my problem and sorry form my english

 

Mathf.DeltaAngle

 

thx a lot i've searched for this all night and found everything except this method

 

Yeah. I wrote my own version of it once.

Then I found it and slapped myself in the back of the head.
