I often find that floating-point data doesn't compress much, but that
ASCII representations of the same data compresses to a file smaller
than the binary one. This is with gzip/bzip2, so we're talking
dictionary-based compression -- and it's easy to imagine why this
might be true. I've never seen any float-point-oriented compressor
like the ones specialized for photos (jpeg, etc.)
