title: Round last 2 digits of double
body: <p>I have a double looking like this:</p>
  
  <pre><code>0.04251789
  </code></pre>
  
  <p>And it should look like this: </p>
  
  <pre><code>0.04251700
  </code></pre>
  
  <p>No matter what the last two digits are they shall be replaced by 00's;
  It is important that the last two digits are not lost but replaced by 00's. </p>
  
  <p>So this:</p>
  
  <pre><code>0.042517
  </code></pre>
  
  <p>would be wrong.</p>
  
  <p>What is the fastest way to accomplish that?</p>
