hi all,
absence of numpypy.nan prevents creating lots of highly important
funcs like isnan, nanmin, nanmax, nanargmin, nanargmax, nansum etc. I
cannot guarantee I would immediately provide them, especially for
multidimensional arrays, but, at least, I (or other programmers) could
create temporary replacements for the absent yet funcs in their own
code (for example, only for 1-dimensional or at most 2-dimensional
arrays), making their code working in PyPy right now.
So could you put the number into numpypy, or there are some difficult
problems with it?
I see nan is somehow present in pypy code, but I cannot acces it from
neither numpypy nor pypy:
