\subsection{Supporting Floating Point Data}
Packing and unpacking floating point data,
i.e. \code{Packer.pack_float}, \code{Packer.pack_double},
\code{Unpacker.unpack_float}, and \code{Unpacker.unpack_double}, are
only supported with the helper built-in \code{_xdr} module, which
relies on your operating system having the appropriate XDR library
routines.
If you have built the Python interpeter with the \code{_xdr} module,
or have built the \code{_xdr} module as a shared library,
\code{xdrlib} will use these to pack and unpack floating point
numbers. Otherwise, using these routines will raise a
\code{ConversionError} exception.
See the Python installation instructions for details on building the
\code{_xdr} module.
