Hey, I just realized we have an [atanh] object for cyclone, I actually did that one myself, and I just tested, it's working on windows!

here's the source https://github.com/porres/pd-cyclone/blob/master/cyclone_src/binaries/control/atanh.c

so, definitely, those functions may exist for windows, not sure what building system you're using, but it may need an update
