If your Perl supports extended double precision floats natively, then you can unpack them using the D pack code. Quoting pack's documentation, D is used to pack/unpack the following:

A long double-precision float in the native format. (Long doubles are available only if your system supports long double values _and_ if Perl has been compiled to support those. Causes a fatal error otherwise.)

Otherwise, I'm curious as to what you're expecting to get. Are you expecting a double, a string or a Math::BigFloat?

If you can read those floats in C, one solution would be to write a conversion routine in C and call it via XS or Inline::C.
