For example:

The answer is in closed form, but I can't convert it to a float. At least:
integrate(sin(2*x),x=-%pi/3..4*%pi/7)::Float
Try
numeric integrate(sin(2*x),x=-%pi/3..4*%pi/7)
I get 0.20048...
I think that is a good solution. But one thing to keep in mind perhaps
for later use is that often when
integrate(sin(2*x),x=-%pi/3..4*%pi/7)::Float
fails, the following similar coercion will work
integrate(sin(2*x),x=-%pi/3..4*%pi/7)::Expression Float
I think the issue is a certain weakness in Axiom's system of coercions.
Don't you find a strong typed CAS is nice for mathematics
even if the final user is a little bored...
Francois, could you expand this comment? I am not sure what point you
are making when you say bored. :-)
