> Project: Ignite
> Issue Type: Bug
> Components: sql ai3
> Reporter: Andrey Mashenkov
> Assignee: Pavel Pereslegin
> Priority: Major
> Labels: ignite-3
>
> For now, in come cases queries, which uses `{{{}FLOAT`{}}} or `DOUBLE`, may
> return inconsistent results for {{`NaN`}} values.
> * `{{{}SELECT MAX(f)`{}}} returns {{`NaN`}} even if there is another
> non-null values.
> * `{{{}SELECT MIN(f)`{}}} returns minimal value if there smth else except
> {{`NaN`.}}
> * `{{{}SELECT f ... WHERE f > 0`{}}} omit {{NaN}} values as well as `nulls`.
> * `SELECT f .. GROUP BY f` returns a single group for `NaN` values.
> Let's validate this behavior and fix if needed, or explain why all results
> are valid.
