title: Rounding in numpy?
body: <p>I have strange problem with python pandas and numpy.</p>
  
  <pre><code>&gt;&gt;&gt; np.float64(1) * np.float64(85000) * np.float64(7.543709)
  641215.26500000001
  
  &gt;&gt;&gt; round( np.float64(1) * np.float64(85000) * np.float64(7.543709), 2 )
  641215.26000000001
  
  &gt;&gt;&gt; np.round( np.float64(1) * np.float64(85000) * np.float64(7.543709), 2 )
  641215.26000000001
  </code></pre>
  
  <p>How to round to get correct result 641215.27?</p>
