Hi James, * James Cloos <cloos@jhcloos.com> [2025-05-16 19:15]:
i took a look at all of the r-devel archves. it is clear my memory about separation NA from nan was not about R.although those archives do talk about avoiding sending NA or nan to BLAS. (i found a related post from me back in 2010...)i wonder whether the NA discussion i recalled may have been about julia? if so it was before they dropped mainglists in favour of discourse ☹.
Thanks for this clarification. Best, Rafael
