> Is this expected? It's not super clear from the assert message, but so it is the "null" that is different (see my inline comment). As Alenka mentioned above, that is indeed expected (and tested on the C++ side) behaviour. In general, predicate functions (checking something, returning a boolean) propagate nulls (in the idea of "you don't know the value, so you also don't know if it is NaN or not, so whether it should be True or False). (one exception on that rule is of course `is_null` to check for nulls itself) -- This is an automated message from the Apache Git Service.
