force numerical eval of exp(%e)



One more thing: Some expressions fail to evaluate to a float even when 
numer 
is true

(C1) %e^%e, numer : true;
(D1) %E^%E

One way to get a float is to map 'float onto the expression. 
-
(C2) fullmap('float,%);
(D2) 15.15426224147926

Probably a trivial q but can't seem to find an answer in 
the documentation --

How does one absolutely force maxima to evaluate expressions numerically
(floats) at all levels of an expression?  I am working on function
expansions that have lots of nested exponentials and logs.
The problem is that the %E's  multiply like rabbits and I need to cook 
them down.

I won't list all the failed attempts, but so far I haven't hit on 
any combination of (fullmap, float, ev, numer, fullratsimp) that works.

                                 Thanks,
                                                 Steve
