title: excel number format - varying decimal digits
body: <p>I'm trying to set a special cell number format with theses rules:</p>
  
  <ul>
  <li>display percentage</li>
  <li>display at max 3 digits (decimal + integer part)</li>
  </ul>
  
  <p>So I can display 100% or 99.3% or 1.27%
  but not 100.9% or 100.27% or 99.27%.</p>
  
  <p>Of course, I can have negative number (-27.3%) and it does not affect my rules.</p>
  
  <p>I've try with the cell formating option without success:</p>
  
  <pre><code>[&lt;1]0.00%;[&lt;10]0.0%;0%
  </code></pre>
  
  <p>Because it seemed that excel (2010) does not support more than 2 conditions in cell formating (and so I can't expand it to manage negative number...)</p>
  
  <p>It there anyway to do what I want?</p>
  
  <p>Thanks</p>
