Hum? It outputs decimal numbers by default.
And it can print both odd and even numbers. ;-)
I use dc quite often in shell scripts to calculate all
kinds of things. It's very useful, and it's portable.
(Except for the "P" command which depends on the byte-
level representation of numbers on the respective
platforms, thus it is not portable.)
By the way, I even think that dc is turing-complete.
I haven't tried to prove it, though. :)
