title: How do I store a double (64-bit floating point) or float in the Windows registry?
body: <p>I want to store a <code>double</code> (64-bit floating point) into the Window registry.  What's the best way to go about it?</p>
  
  <p>Possible options: both a <code>long</code> and a <code>double</code> in a 64-bit compiler are 64-bit values so one option is to convert the double to it's 64-bit representation and store it as a registry "qword".  Another option is to store it as a binary stream.</p>
