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

Subject: [Maxima] force numerical eval of exp(%e)
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
