[En-Nut-Discussion] Floating point support for Ethernut 3.0?

Hi Mark,

Nut/OS will not provide floating point support, but
the libraries that come with the compiler do.

The only problem for Nut/OS is, to convert a float
to its ASCII representation for printf(). However,
you may find ways to properly print floats converted
to integers.
