title: Formatting Numbers as Strings with Commas in place of Decimals
body: <p>I have the following number: <code>4.3</code></p>
  
  <p>I'd like to display this number as <code>4,3</code> for some of our European friends.</p>
  
  <p>I was under the impression that the following line would do the trick:</p>
  
  <pre><code>string ret = string.Format("{0:0,0}", 4.3); // returns "04", not "4,3"
  </code></pre>
  
  <p>Am I using the incorrect string?</p>
