title: How to round without Math#round?
body: <p>So it's easy to round the tenths place with just doing something like:</p>
  
  <pre><code>int y;
  double x = 2.5;
  
  y = (int) (x+.5);
  </code></pre>
  
  <p>but how would you go about rounding to the hundredths or even thousands place without using <code>Math.round()</code>? </p>
