| Apr 10, 2021 at 7:39 | comment | added | Peter Cordes | @Ausername: Yes, it's very possible to solve without builtin complex number support. Those languages have to implement it somehow, e.g. complex multiply of c1a + i * c1b times c2a/b is real = ((c1a * c2a) - (c1b * c2b)) imag = ((c1b * c2a) + (c1a * c2b)). A power function producing a complex result for negative bases is even more of a chore to implement manually, so I'm not surprised few people have. (Although apparently not as bad as I thought if you can use sin and cos as building blocks; implementing those in terms of basic operations like + - / * and lookup tables is not simple) | |

| Apr 8, 2021 at 12:25 | comment | added | Federico Poloni | Complex roots are multi-valued in general, so how do you define exactly $(1-\phi)^{p/q}$? Is any of the $q$ possible results valid? | |

| Apr 7, 2021 at 16:48 | comment | added | pxeger | @Ausername Besides the fact this has been answered in JS already, it's pretty obvious this is possible in JS given it's plainly turing-complete | |
