Yes, indeed that works!  Also for functions called from main().
I almost tried this, but with the bool declaration...
Thanks a lot!

I wonder if section 12.2 of the manual should be modified?
The behaviour maybe  depends on compilers and systems.

By the way, I think it most of the time is a bad idea to turn on this
option. Usually underflow is a signal that some lowprecision
variables have contaminated your calculation.
