i suggest making the buffer in which you operate "unibyte", arranging
for the insertion of external data in the buffer (for example, in a
subprocess output handler) to use the `raw-text' character encoding, and
using bindat.el on the buffer for the (un)packing.  more info at:

(info "(elisp) Selecting a Representation")
(info "(elisp) Byte Packing")

these references are from cvs emacs.  i know the latter doesn't exist,
and don't know about the former, for released elisp.info pages.

presently, bindat.el doesn't (yet?) have floating-point support.
it would be cool if someone (perhaps you?) were to add that.
