While those who make heavy use of floating-point computations in
embedded sytems probably go for systems with hardware support for
floating-point calculations, there are plenty of systems without such
support out there.
And the existence of soft float implementations indicates that there is
a real need for doing floating-point computations on systems without
hardware floating-point support. I'd like to know a bit more about that.

* What kind of computations do people use soft float for? Any real-world
examples?
* Which types of soft float do they use? IEEE 32- or 64-bit? Some other
C standard-compliant type? 16-bit IEEE? Other 16-bit?
