Not trying to dredge up this topic again, but I can't quite seem to
find the "definitive" method of making this test. Currently my
programs are just throwing errors and stopping, I would like to be
able to detect when this happens, discard the results, and then move
on to the next iteration of my program.
Luiz's lmathx [1] provides isnan and fpclassify if you prefer which is
certainly definitive as it just gives you access to the C99 math
additions. Alternatively, testing x ~= x on a Lua number is correct
(and this is how the internal luai_numisnan macro is defined).
