Perhaps as a mid point M-x calcul RET ?  ;-)

Actually, I understood M-x calc RET; where I may have misunderstood
you is when you mentionned 'batch'. I thought about: emacs -batch

I wasn't aware it was a symbolic calculator too.  This means the
hidden part of the iceberg is bigger than just its user interface and
makes it indeed worthwhile to try to call up from your own emacs lisp
code.
