I don't see a real problem here: both cmath.sqrt(-1) and (-1)**0.5 are producing good approximations to the correct result, which is about as much as you can hope for in general with floating-point algorithms.
I wouldn't want to start special-casing the complex power algorithm to produce expected results for given bases or exponents; the code is complex enough as it is.
Patches to improve the general accuracy of complex.__pow__ would be welcome.
Closing as won't fix. |
