Problem 43708. Replace all odd numbers with NaN

Please use isequaln instead of isequal when checking equality for NaN values.

P.S. I accidentally clicked "Like" to this problem and then realized that the "Unlike" function doesn't work. Also, the "Delete" comment function still doesn't work despite the fact that this has been reported since September or even earlier.

This problem has been improved and the test suite fixed.

Peng, the problem with deleting your own comments has been an issue for three or four years now. I didn't realize that Unlike isn't working either, though.

James, Peng, that surprises me. I thought it doesn't work since the new layout introduction. I had no problems with deleting my comments before. (or it's just a typo, and James meant months)

James, Peng, I have also reported these bugs (unable to "delete", unable to "unlike"), and can confirm that (at least for me) they are still a problem. A further complication is that there is no dedicated 'channel' for reporting Cody issues. Perhaps also a Cody-specific discussion forum would be helpful. —DIV
