title: Pipe `|` character in formulas (functions)
body: <p>I ran across the following in an example describing RANK function in Apache OpenOffice Calc:</p>
  
  <pre><code>=RANK(5; {3;5|2.6;1}; 1)
  </code></pre>
  
  <p>I cannot figure out what the pipe character does. I have been playing around with it a little bit and still scratching my head:</p>

  <p>Can anyone shed some light?</p>
