The following unary arithmetic operators of
numpy.ndarrayhave been simplified and improved:__abs____invert____neg____pos__These will now return shape-type and the specific
ndarraysubtype if relevant. Type-tests were added to confirm the correct behavior, which required working around a tricky mypy bug (python/mypy#14070).Additionally, the typing errors in the numeric builtin-type-conversion methods of
ndarrayhave been fixes, so that pyright/pylance will now also be able to infer their return types:__index____int____float____complex__These changes should in general be backwards-compatible.
