[Rcpp-devel] NA_REAL in RcppParallel

[Dirk Eddelbuettel]

For the particular case of 'not finite' on floats I also found that I could
resort to the standard NaN which IEEE arithmetic supports.  Of course, this
will then be a NaN in R and not a NA where you might want the latter.  But at
least it stays cleanly away from R which may help in the multithreaded
contexts.
