[fpc-pascal] Floating-point number representation on various platforms

While writing a paper (several years ago) about the traps of using
floating-point numbers, I prepared a unit FloatView to "play" with
the internal representation according to the IEEE Std, including
to print it in various formats.
Initially, I made this work for the Linux/i386 platform only. Later,
I tweaked it for Mac OS X (different byte order). It supports only the
IEEE Std Single and Double format (not Extended).
I would like to make this unit available, but hesitate, because of
its platform dependence (and currently limited platform support).
Question 1: Is there an interest in such a unit?
Question 2: Any suggestions as to how to make it more platform independent,
or how to support multiple platforms in an easy way?
Looking forward to some feedback,
