Replying to [comment:3 was]:
> To me, using signal handling instead of simply checking whether or not
the float is a nan (using isfinite) is a much worse solution to this
problem. Do you think otherwise, and if so, why?
I was not proposing it as a solution to this problem, just to add the
signal handling in addition as an extra safeguard.
Ideally there would have been `sig_on()`/`sig_off()` already, such that
this ticket would say:
{{{
sage: float('nan') > 1
Tracback (most recent call last):
...
RuntimeError: Floating Point Error
}}}
which doesn't crash Sage.
