I need to serialize an ieee compliant 64 bit floating point number, most often used as a Double in C.

I'm guessing that the value I need to serialize is CDouble, but Put supports putWord64*  .

How do I convert Double to Word64 while ensuring that it is in the format of CDouble?

Is this the right approach? If so, how is this done?
