Ian Cook created ARROW-13367:
--------------------------------
Summary: [C++] Add option to is_null kernel to return true on NaN
Key: ARROW-13367
URL: https://issues.apache.org/jira/browse/ARROW-13367
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Reporter: Ian Cook
Currently the {{is_null}} C++ kernel returns {{false}} on {{NaN}} values.
Consider adding a boolean option to this kernel that could be used to make it
return {{true}} on {{NaN}} values. This would allow the code added in
ARROW-12055 to be much simplified.
