Remap Value

Ok im trying to write a script that will remap a value to a new range. In the example, the 'currentt' value will always be between zeroAngle and 180Angle. These are subject to change at runtime. I need a script that will translate the current int a corresponding value. ZeroAngle becomes 0 and 180Angle becomes 180.

Code (csharp):

1.  
2. public HingeJoint H;
3.     public float current=0;
4.  
5.  
6.     public int ZeroAngle = -45;
7.     public int 180Angle = 128;
8.     // Use this for initialization
9.     void Start () {
10.    
11.     }
12.    
13.     // Update is called once per frame
14.     void Update () {
15.         float RemappedValue = Remap (current);
16.     }
17.  

 

Something like this?

JUST like that thank you.

Seems such a simple thing to get stuck on. Cheers
