title: How can I round a number in JavaScript? .toFixed() returns a string?
body: <p>Am I missing something here?</p>
  
  <pre><code>var someNumber = 123.456;
  someNumber = someNumber.toFixed(2);
  alert(typeof(someNumber));
  //alerts string
  </code></pre>
  
  <p><strong><em>Why</em></strong> does <code>.toFixed()</code> return a string?</p>
  
  <p>I want to round the number to 2 decimal digits. </p>
