\begin{axiom}
solve(x+1.1,0.001)
\end{axiom}

I'm confused. Perhaps that's because I expect Axiom to behave like other
similar software,
but what is the meaning of
solve: Polynomial Float->List Equation Fraction Polynomial Float
when we're trying to solve an equation with real coefficients? Doesn't an
accuracy need
to be specified? (and there doesn't seem to be a default).
Also, while solve(x+1.1) "works", so to speak, solve(x^2 - 1.234) returns a
warning.
Very bewildering to a beginning user!
My impression, from looking at the algebra library, is that Axiom does not
appear to handle
(i.e. solve) polynomials with real coefficients. It produces them as results,
but doesn't accept
them as inputs. Is this basically correct?
