title: Rounding the result of division in Javascript
body: <p>I'm performing the following operation in Javascript:</p>
  
  <blockquote>
    <p>0.0030 / 0.031</p>
  </blockquote>
  
  <p>How can I round the result to an arbitrary number of places? What's the maximum number that a <code>var</code> will hold?</p>
