title: unity Mathf.PerlinNoise not between 0 and 1
body: <p>Does anybody know why this: </p>
  
  <pre><code>    Debug.Log(Mathf.PerlinNoise(190911.45f, 2290937.40f));  
  </code></pre>
  
  <p>gives me: 1.044323 It should have been between 0 and 1 isn't it?﻿ </p>
  
  <p>And if it can get bigger than 1 can it get smaller than 0? I'm making a map with sprites and everything works :) except that i get empty spaces if the value is bigger than 1.</p>
  
  <p>I use a random seed, that's why the numbers are so big, if you wondering.</p>
  
  <p>I hope someone can help me out, Thanks :)</p>
