In pandas it is a different data type ('Int64' vs 'int64'), so it makes
perfect sense for me to mention
it in this article provided I missed it in the main Numpy Illustrated one.
I didn't have a chance to use
them on my own and I've heard from some people that they don't use
the masked array, for some
reason, too. Do you know if Pandas uses ma internally or they have their
own implementation?
Thanks and regards,
