atan2(x,x)



I am certainly interested. What do you have in mind?

Well, asksign certainly is annoying.

I wrote some experimental code (share/contrib/noninteractive)
which captures asksign queries and turns them into conditional
expressions. It sort of works; you can see some successful
examples in the comment header for noninteractive.mac.

However, I think it to banish asksign will require a different
approach. I can say more about that if anyone is interested.

FWIW
