title: Python conversion from c_double to float
body: <p>I am new to Python. I would like to know what would be the best way to convert a c_double (from ctypes) to a float. My code is working, but I would like to know if there is a pythonic way to do it. What I currently do is:</p>
  
  <pre><code>FloatValue = float( str(d_Val)[9:( len( str(d_Val) ) )-1] )
  </code></pre>
  
  <p>Where <code>d_Val</code> is <code>c_double(-10.0)</code>, and I want to keep <code>-10.0</code>
  Working with Python 2.7 under windows.</p>
