Subject: Signalling NaNs for floating point initialization?
Date: Thu, 17 Dec 1998 08:35:00 -0000 [thread overview]
Message-ID: <199812171635.RAA03621@mvmap66.ciw.uni-karlsruhe.de> (raw)
One of the most useful options on an SGI Fortran compiler I've worked
with some years ago was to set all floating point variables to
signalling NaNs upon startup of a program, which helped a lot in
converting old code and in finding quite a few bugs in new ones.
What do you think about implementing this in g77?
