OK. As a digression, I think it is easy to get the wrong impression of
Sage that it is for "symbolics" vs. "computations". The reality is that
the symbolics has been one of the *weaker* aspects of Sage (though
steadily improving) -- the strong aspect is computations, but with
elements that NumPy doesn't handle efficiently: Arbitrary size integer
and rationals, polynomials (or vectors of their coefficients if you wish
-- just numbers, not symbols), and so on.
So the Sage design is very much about computation, it is just that the
standard floating point hasn't got all that much attention.
