Benefit of treating NA and NaN differently for numerics
Hello,
I notice in main/arithmetic.c, that NA and NaN are encoded
differently(since every numeric NA comes from R_NaReal which is
defined via ValueOfNA)
. What is the benefit of treating these two differently? Why can't NA
be a synonym for NaN?
Thank you
