Same goes for NZERO and PZERO.

I can make a pull request, if you'd like. Just let me know if you prefer that I've replaced these constants with the "suggested replacements", or make them conditional to NumPy version (and possibly add "suggested replacements" to the test as well).

[ijl]

It's compatible in 3.10.3. Thanks for the report.

[mgorny]

Thanks. I can confirm that the tests pass for me now!
