title: How should I parse Infinity with Double?
body: <p>If I try</p>
  
  <pre><code>Double.Parse("Infinity")
  </code></pre>
  
  <p>I get</p>
  
  <pre><code>Double.Parse("Infinity") threw an exception of type 'System.FormatException'
  </code></pre>
  
  <p>Why? And what should I do if I want to parse it anyway and get a Double with the value Infinity?</p>
