title: Python to C# StongBox[Single]
body: <p>I've used IronPython to add a reference to a C# dll.  I'm attempting to use a method in the DLL which requires an argument of type:</p>
  
  <pre><code>out float tempValue
  </code></pre>
  
  <p>When I pass a python float object to the method I get the following traceback:</p>
  
  <pre><code>Traceback (most recent call last):
    File "MeasurementComputing.py", line 20, in &lt;module&gt;
  TypeError: expected StrongBox[Single], got float
  </code></pre>
  
  <p>My questions are:</p>
  
  <ol>
  <li>What is a StrongBox[Single]</li>
  <li>How do I create such an object in python to pass to the C# method.</li>
  </ol>
