Is it possible to round a perlin noise value to 1 or 0?

Even though no one is answering I'm still gonna give updates. I've made a new script, but with basic noise, not with perlin noise.

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class SimplexNoise : $$anonymous$$onoBehaviour {
 
     float xCoord, yCoord;
     public int width, height;
     public GameObject rockTile;
     float noise;
     Vector3 pos;
 
     // Use this for initialization
     void Start () {
         GenerateTerrain ();
     }
         
     void GenerateTerrain()
     {
         for (xCoord = 0; xCoord < width; xCoord++) {
             for (yCoord = 0; yCoord < height; yCoord++) {
                 noise = Random.value;
                 pos = new Vector3 (xCoord, yCoord, 0);
                 if(noise < 0.5f)
                 {
                     noise = 0;
                 }
                 else{
                     noise = 1;
                     Instantiate (rockTile, pos, Quaternion.identity);
                 }
             }
         }
     }
 }

Basically it does what I want, but I'm ending with a basic white noise "texture".

Note: If you try this start with the width and height at 10, then increase it accordingly to your machine, because it will crash unity.
