title: F# int64 to int
body: <p>How can I convert an <code>Int64</code> to an <code>Int32</code> type in F# without using the <code>Microsoft.FSharp.Compatibility.Int32.of_int64</code>?</p>
  
  <p>I'm doing this because interactive doesn't seem to work when I try:</p>
  
  <pre><code>open Microsoft.FSharp.Compatibility
  </code></pre>
  
  <p>With <code>FSharp.PowerPack</code> added as a reference it says: </p>
  
  <blockquote>
    <p>error FS0039: The namespace 'Compatibility' is not defined.</p>
  </blockquote>
  
  <p><strong>Edit:</strong> Does anyone have an answer to the question?  The suggestions about the int types are useful and informative, but I'm having the same issue opening the powerpack namespace in F# interactive.</p>
