	mathlib.c 
Log Message:
Melchior points out that NaN/Inf behavior is not platform-independent.
So toss a runtime error ("floating point error") when any of the math
library functions produce a non-finite value.  Note that these are not
the only locations that can do that (simply dividing by zero will
produce an Inf), but it's still proper behavior.
