numer: true$
fullmap(ev, %o<something>);
will evaluate recursively anything that can be evaluated numerically.
For example:
niobe% maxima
(%i1) a:sin(b)$
(%i2) b:cos(c)$
(%i3) c:1.2$
(%i4) a;
(%o4) sin(b)
(%i5) ev(a);
(%o5) sin(cos(c))
(%i6) numer:true;
(%o6) true
(%i7) %o5;
(%o7) sin(cos(c))
(%i8) fullmap(ev,a);
(%o8) .3544798670095258
