Once we have that, I don't think we need cuberoot. The function should only accept (positive?) integer arguments n. For even n it could have the usual behaviour, for odd n it could do the sign thing. It's possibly nicer to implement it as a symbolic function with custom numerical evaluation rather than a python function that produces a relatively cryptic symbolic expression. It should be documented as the "real-valued n-th root of real-valued expressions".
Please look whether we should have nthroot(n,x) or nthroot(x,n), or perhaps even nthroot[n](x) [I hope not]. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
