Subject: [Rd] Benefit of treating NA and NaN differently for numerics
Message-ID: <1e7471d50912311243s6e681390n1f27ea0fde3c8e3e@mail.gmail.com>

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
