title: Output_precision(); Octave
body: <p>Hi after calling this code (Octave) I get an answer with 7 digits of precision, I need only 6. It is worth mentioning that on different data-set the output is normal(with 6 digits);</p>
  
  <pre><code>output_precision(6);
  Prev
  </code></pre>
  
  <p>output:</p>
  
  <pre><code>Prev =
     0.1855318
     0.2181108
     0.1796457
  </code></pre>
