title: What are the possible usage scenarios for Number.EPSILON?
body: <p>I saw the documentation of JavaScript on MZO and I was read this part:</p>
  
  <blockquote>
    <p>The Number.EPSILON property represents the difference between 1 and the smallest floating point number greater than 1.</p>
  </blockquote>
  
  <p>also I saw this example on the page:</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-js lang-js prettyprint-override"><code>var result = Math.abs(0.2 - 0.3 + 0.1);
  
  console.log(result);
  // expected output: 2.7755575615628914e-17
  
  console.log(result &lt; Number.EPSILON);// expected output: true</code></pre>
  </div>
  </div>
  </p>
  
  <p>Okay I understand that I can use this function for see the difference between two floating point number but I cannot see a use in a website</p>
