Unity reading decimals

Hello,

I have this code that I inherited from a friend,( that I am also asking) but in case he is too busy I was hoping maybe this is a simple problem someone here can answer.

Basically I have this code that can read a CSV file and instantiate the data based on x y z and scale of y. But the problem I am having is that it is not reading decimal points. Does anyone know if this is a simple fix ?

Here is the code:

 using UnityEngine;
 using System.Collections;
 
 public class Cube : MonoBehaviour {
     
     //This code is used to parse a CSV file and also to spawn objects based on that CSV fi
     // Big thanks to Seth Iacangelo aka Dark Shot of FF XIV
 
     public TextAsset csvFile;
     public GameObject prefab;
 
     private int index = 0;
 
     private int[] x;
     private int[] y;
     private int[] z;
     
     void Start(){
         Longitude();
     }
 
     void Longitude () {
         print (csvFile);
         string[] numberArray = csvFile.text.Replace("\n"[0],","[0]).Split(","[0]);
 
         int length = (numberArray.Length - 1) / 3;
         x = new int[length];
         y = new int[length];
         z = new int[length];
 
         for(int i = 0; i < numberArray.Length - 1; i++){
             switch (i%3) {
                 case 0:
                     x [index] = int.Parse (numberArray [i]);
                 break;
                 case 1: 
                     y [index] = int.Parse (numberArray [i]);
                 break;
                 case 2:
                     z [index] = int.Parse (numberArray [i]);
                     string name = index.ToString();
                     GameObject instance = Instantiate(prefab) as GameObject;
                     instance.transform.position = new Vector3(x[index],y[index],0);
                     instance.transform.localScale += new Vector3(0,z[index],0);
                     instance.name = name;
                     index ++;
                 break;
             }
         }
     }
 }
