[issue36934] C API Function PyLong_AsDouble Returning Wrong Value

Tim Peters added the comment: Note that this pure Python gives the same result: >>> "%.0f" % float(1639873214337061279) '1639873214337061376' That's not surprising: int -> float conversion is limited to the precision of a Python float, which is a C double, which is almost certainly just 53
