2017-12-07 09:18:27 +0100 | asked a question | Change Precision on complex_roots() I am trying to find the complex roots of the polynomial poly = x^7 - 6 But when I do poly.complex_roots(), the system gives: Apparently there are options for how much precision you want when computing roots -- one option is to use Pari, which is the high-precision option, and the other NumPy, which is the low-precision option. The default is set to use Pari, which apparently overloads when I try to compute the roots of this polynomial (and many others as well, this polynomial is just one example). How do I change the complex_roots() function to get lower-precision roots? Alternatively, how do I deal with the PariError? |
