I can confirm that the bug is present also for an intel-based linux system.
In my opinion it is absolutely not useful to define a DF mode type on the AVR
platform. Both excecution time and memory footprint would probably so large
that they will not be of any relevance. What one could possibly consider IMHO
is the implementation of a 3-Byte floating-point type with a 16 bit mantissa.
Is there any know workaround so far?
Yours,
Björn
