--- Comment #2 from Aleix Pol <aleix...@kde.org> --- KAlgebra doesn't use qalc, yet we probably use the same API hence the same behaviour. https://en.cppreference.com/w/cpp/numeric/complex/pow Even wolfram shows it: https://www.wolframalpha.com/input/?i=%28-8%29%5E%281%2F3%29&assumption=%22%5E%22+-%3E+%22Principal%22 Under the "decimal approximation" section. Now this doesn't make much sense, will need to investigate further why it happens, brush off some knowledge I haven't used in a while... -- You are receiving this mail because: You are watching all bug changes.
