title: Simple IF with AND and numeric comparison not resolving correctly
body: <p>I have the following formula:</p>
  
  <blockquote>
    <p>=IF(A14>=7 &amp; A14&lt;=18,"I","E")</p>
  </blockquote>
  
  <p>It resolves to <code>I</code> (true) when A14 is 3 and it should resolve to <code>E</code> (false) as a matter of failing the left <code>if</code> criterium.</p>
  
  <p>I am using <code>LibreOffice Calc</code> on <code>Ubuntu 14.4</code>. What am I doing wrong?</p>
