Comment(by ddrake):
This passes all doctests and -- with my minimal knowledge of Cython and
MPFR -- the code looks very good. I see that the relevant function
automatically coerces to complex numbers; would it make sense to add a
doctest for negative ints? And maybe zero, to be complete?
{{{
sage: int(-2)^(0.333333)
0.629961522017056 + 1.09112272417509*I
sage: int(0)^(1.0)
0.000000000000000
sage: int(0)^(0.0)
1.00000000000000
}}}
My guess is that we'll need to test this on a bunch of platforms to suss
out any numerical noise. But other than that, I can give this a weak
positive review -- we need someone who knows MPFR and Cython better than I
do. (Or, I need to learn more of those things...)
