Lua does not depend in IEEE 754 and so does not mention NaN (of Inf) at all.

Is it? I mean, the code below does work (and prints nil) but it wouldn't
print anything else even if you did put a value associated to a Nan key.
a=0/0 ; t={} ; print(t[a])
Anyway, NaN is a mess that we don't want to get into.
