Despite whether we are doing so deliberately (most likely not), I don't think emitting `-inf` or `inf` is desirable for an all-NaN array. The proposed returning NaN sounds reasonable. I think current undesirable behavior is because we initialize our running min/max as `-inf`/`inf`. And by definition `std::fmin/fmax(non-NaN, NaN)` always emits `non-NaN`. I think I can work on a fix. -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
