[C#] 2D elliptical Orbit - Non incrementing Variable

So I'm having an issue with the variable T in this code, for some reason it is not being incremented and I just cannot figure out why. For those wondering this is to be used for elliptical orbit in a 2D environment. For more precise numbers I should be using doubles however I'm unaware of how to cast as doubles within unity. All attempts have failed. More interested in resolving Angle. I apologize in advance for any issues with reading. Will be here all day if more details are needed.

 public class Orbit : MonoBehaviour
 {
     private int minD; // min orbital distance of this object from it's parent or barycenter
     private int maxD; // max orbital distance of this object from it's parent or barycenter
     private int massObj; // mass of this object
     private int massTar; // mass of the orbital parent, (mass of other star if binary star pair)
 
     private float G = 0.0000000000667408f; // Gravitational Constant
     private float AU = 149597870700f; // Meters
     private float c = 299792458f; // Meters/Second
 
     private float a; // Semi-Major Axis
     private float b; // Semi-Minor Axis
     private float P; // Period, overwritten by period, if period is non-zero
     private float e; // Eccentricity, zero means a circular orbit
     private float M; // Mean Anomaly
     private float t; // Current world time
     private float E; // Eccentric anomaly
     private float o;
 
 
     // Use this for initialization
     void Start()
     {
         minD = 5;
         maxD = 50;
         massObj = 100;
         massTar = 100;
 
         a = (minD + maxD) / 2;
         b = Mathf.Sqrt(minD * maxD);
         P = Mathf.Sqrt((4 * Mathf.Pow(Mathf.PI, 2) / (G * (massObj + massTar))) * Mathf.Pow(a, 3));
         e = (maxD - minD) / (maxD + minD);
     }
 
     // Update is called once per frame
     void Update()
     {
         t = Time.time;
         o = t % P;  /* time on orbit */ 
         float M = 2 * Mathf.PI / P * t;
         float E = M;
         for (float k = 0; k < 10; k++) { E = M + e * Mathf.Sin(E); }
         float r  = a * (1 - e * Mathf.Cos(E)); /* current radius */
         float T  = Mathf.Acos((a * Mathf.Cos(E) - a * e) / r); /* current angle */
         
         if (o > (P / 2)) { T = -T; } // This lets us resolve the OTHER half of the orbit 
 
         Debug.Log("Period: " + P);
         Debug.Log("Orbit: " + o);
         Debug.Log("Radius: " + r);
         Debug.Log("Angle: " + T); // This is always zero! Gah!
         Debug.Log("Time: " + t);
         transform.position = new Vector3(r, 0, 0);
         transform.RotateAround(transform.parent.position, Vector3.forward, T / Mathf.Deg2Rad * Time.deltatime);
     }
