In ciforth:
I added floating point support using the FPU with relatively
little work, especially because the transcendentals are easy.
I suspect that it might be not standard. E.g. F+ exhibits
more precision in 80 bits, and we are supposed to use
either IEEE 32 or 64 bits. Apparently I'm in good company
(iforth and vfxforth).
What does the language lawyers say?

Your are in luck: the internal representation of fp numbers is
implementation-defined.
However fp-alignment restrictions must be observed on affected
systems, which in itself is a rather superfluous requirement
since most such systems would crash anyway.
