There's no IEEE-754 support in any *current* Fortran Standard - however,
the upcoming F2K Standard _does_ provide for this - see the F2K entry in
our Readings Section, Chapter 15. I'd rather try to implement something
that has a chance to become a standard than yet-another-extension to
Fortran 77 ...
OTOH, discussions about what IEEE-754 support in Fortran *means* haven't
died down yet ...
