title: Haversine formula Unity
body: <p>So I'm trying to use the haversine formula in Unity to get the distance between two different points (latitude and longitud given). The code is working (no errors) but I keep gettting a wrong result. I followed the entire formula so I don't really know where the math/code problem is. Any idea?</p>
  
  <p>Here's the code:</p>
  
  <pre><code> public float lat1 = 42.239616f;
   public float lat2 = -8.72304f;
   public float lon1 = 42.239659f;
   public float lon2 = -8.722305f;
  
   void operacion(){
   float R = 6371000; // metres
   float omega1 = ((lat1/180)*Mathf.PI);
   float omega2 = ((lat2/180)*Mathf.PI);
   float variacionomega1 = (((lat2 - lat1)/180)*Mathf.PI);
   float variacionomega2 = (((lon2 - lon1) / 180) * Mathf.PI);
   float a = Mathf.Sin(variacionomega1/2) * Mathf.Sin(variacionomega1/2) +
               Mathf.Cos(omega1) * Mathf.Cos(omega2) *
               Mathf.Sin(variacionomega2/2) * Mathf.Sin(variacionomega2/2);
   float c = 2 * Mathf.Atan2(Mathf.Sqrt(a), Mathf.Sqrt(1-a));
  
   float d = R * c;
   }
  </code></pre>
