The version I sent this morning is the last change I made. How about if you come the owner of the code for a while. When you are finished, send it back to me, and I will look over everything you have done. I won't work on it until then. This works for me in other ways too, because my life is very busy at the moment. If I do work on code, it will be on casinh/casin. I am looking over the paper by Hull et al, and I am learning a lot from it. One thing I did realize - casin and casinh are essentially the same. If #define reverse(z) cpack(cimag(z),creal(z)) then casin(z) = reverse(casinh(reverse(z))). Unfortunately it is not so nice for cacos/cacosh. I do like the progress we are making, and I appreciate your help very much.
