When I write a simple problem to divide 4.0/MINDOUBLE and run it on a
Sparc10 the result is 'Inf' and this is good because my program doesn't
crash. On my Linux box the same calculation results in a 'floating
exception' and crash.
Is there someway I can get the Linux box to behave like the Sun machine?
I.E. handle floating exceptions as Inf??
(BTW I'm running GCC 2.7.0 and linux v1.3.3 if it matters)

This disables all floating point exceptions. Not sure I like that convention
but many vendors seem to be following it. To turn exceptions back on
selectively ... wait for me to finalize my extended IEEE library some rainy day
during my vacation.

1. floating point exceptions managed in Linux?
Does anybody know if Linux is able to manage floating point
exceptions (in the same way Sun Solaris or IBM RS600 AIX handle
not-a-number NaN, NaNQ, NaNs...)?
Thank you!
