Hi List,
Regarding pw.mac in general. I realize that pw.mac uses algorithms that are not optimal. I think there are better ways
to do many of the things pw.mac does and I am getting closer to an optimal version of pw() but that may not happen right
away or be done by me. Someone else will know a better way to do the same thing and will just modify my code without
telling me. I don't know if using "if" instead of "signum()" is better. I have found two cases in my testing, one in
which "if" works faster and one in which signum() works faster.
