Life may be more simple than I thought, it seems like comipilers have
support for NaN and Inf numbers. Below is a VC++ help page that makes me
think this is the case
Hi,
Just want to make a suggestion. Currently
double x = Null<double>() * 0.01;
produces a valid double, which is confusing (I ran into it when I read
interest rates in %% and then converted to non-percent numbers).
I heard that there is a IEEE standard + libraries for things like NaN, Inf,
etc. It would be nice if Null<numeric> conform to that standard.
Another option is to use Rmath library (a standalone byproduct of R-project)
which seems to handle NaN-s properly, but I don't have first-hand experience
with it.
Thanks, Vadim
