Perl and its handy 'unpack' function can come to your rescue here. See perlmonks.org/?node_id=718410 where there's some examples. – steve Jun 17 at 19:08

Radare is a binary exploration toolkit with nice data-carving features which should allow you to extract the data (and help you figure out the exact storage format and endianness).
