I'm using Emacs 24.5.1 in Cygwin.
In Calc, if I have a number at the top of the stack that I've just computed, what is the easiest way to change the sign of that value? I'd be amazed if there isn't a simple way to do that, but I can't find it after scanning the info.

Sigh. It never fails. No matter how much time I spend looking for something, I find the answer 30 seconds after posting a question about it.
I expected to find info about this in "Stack and Trail", and not "Basic Arithmetic", where I found "n".
