I think it's good when Maxima functions work the same for floats and big
floats.
Maybe you can speed the code somewhat without losing big floats. For RK
using
doubles, users have lots of choices.
Big float complex number arithmetic isn't so nice -- you'll need to expand
products.
And that's slow :(
