I'm always willing to see my mistakes revealed, if it can be done so
eloquently and politely. Unlike some people in this thread, you've been
both eloquent and polite; thank you.

I still maintain that hardware fsin and fcos are valid and valuable for
certain classes of applications, and that we need better options and
documentation -- both of which I'm more than happy to work on. I look
forward to your future comments.
