The feenableexcept() and fedisableexcept() APIs are now provided which let you detect when NaNs appear the moment it happens from anywhere in your program. Tests have also been added for the mission critical math functions expf() and erff(), whose perfect operation has been assured. See examples/trapping.c to see how to use this powerful functionality.
