set ray.point as x, y and z float

Hi! i am trying to get the x, y and z cordinates from a ray into a public float. the script looks like this:

 using UnityEngine;
 using System.Collections;
 
 public class RaytoMouse : MonoBehaviour {
 
     public float distance = 50f;
     public float x = 0;
     public float y = 0;
     public float z = 0;
     //replace Update method in your class with this one
     void FixedUpdate () 
     {    
         //if mouse button (left hand side) pressed instantiate a raycast
         if(Input.GetMouseButton(0))
         {
             //create a ray cast and set it to the mouses cursor position in game
             Ray ray = Camera.main.ScreenPointToRay (Input.mousePosition);
             RaycastHit hit;
             if (Physics.Raycast (ray, out hit, distance)) 
             {
                 //draw invisible ray cast/vector
                 Debug.DrawLine (ray.origin, hit.point);
                 //log hit area to the console
                 Debug.Log(hit.point);
                 
             }    
         }    
     }
 }

my question would be, how can i fill the public float x, y and z to the right coordinates? the debuging already works fine.
