title: Efficient get random whole number between two intervals
body: <p>I use this normally.</p>
  
  <pre><code>var min = 0;
  var max = 1;
  
  console.log(Math.round((Math.random() * (max - min) + min)));
  </code></pre>
  
  <p>It works fine and dandy, but I can't get over thinking that this may be an expensive way of producing this result, does anyone know of a more efficient way?</p>
  
  <p>Or <em>is</em> this the most efficient way?</p>
