title: What does a percentage symbol mean as part of a variable name?
body: <p>I'm just looking at some VB.NET code and I came across this:</p>
  
  <pre><code>Dim var%
  </code></pre>
  
  <p>Later <code>var</code> is set to 0.</p>
  
  <p>What's the purpose of the percent sign (<code>%</code>)?</p>
  
  <p>(Google and SO search failed me)</p>
