title: numpy.rint not working as expected
body: <p>I am trying to find the cause of this result:</p>
  
  <pre><code>import numpy
  result1 = numpy.rint(1.5)
  result2 = numpy.rint(6.5)
  print result
  </code></pre>
  
  <p>The output:</p>
  
  <pre><code>result1-&gt; 2
  result2-&gt; 6
  </code></pre>
  
  <p>This is odd: <em>result1</em> is correct but I <em>result2</em> is not (It has to be 7 because <em>rint</em> rounds any float to <a href="http://docs.scipy.org/doc/numpy/reference/generated/numpy.rint.html" rel="nofollow">the <em>nearest</em> integer</a>).</p>
  
  <p>Any idea? (THANKS!)</p>
