Yes, and even with "c,eval,numer" works. But i was most interested
in knowing if there is a way to force a numerical output. I mean, a
command that do all known substitutions and then evaluate numerically
the variable (the problem in the example i've posted i think it's that
it need another substitution in the chain d->b->10+a->tan(). In this
case it's simple, but if i have a lot of variables it's difficult to
know if a result is still symbolic for a missing value or it's just
unevalueted. Or doing ''c,numer or ev(c,eval,numer) it will suffice in
any case?
thanks,
