New submission from Rohan Prasad :
Hi,
I'm having a weird issue with floats in dictionaries and equality comparison
(see attached screenshot for an example). When I create two dictionaries with a
nan value they pass an equivalence test. However, if I pickle and unpickle one
of the dictionaries they become no longer equivalent. I would expect that the
behavior would be the same irrespective of whether they are pickled/unpickled.
Is there something else I should be doing here or is there a way to easily
resolve this (short of writing custom ways to compare equality)?
