15243 Change algorithm for K.uniformizer(P) jdemeyer "As shown by #14476, it is annoying that the following depends on the hardware:
{{{
sage: K. = NumberField(x^4 - x^3 - 3*x^2 - x + 1)
sage: [K.uniformizer(P) for P,e in factor(K.ideal(5))]
}}}
Moreover, the algorithm for `K.uniformizer()` seems inefficient: instead of calling `idealappr()`, we can simply use the second component of the `pari_prime()` structure. Experiments show that this yields equal results for 32-bit and 64-bit machines (but there is no guarantee)." enhancement closed minor sage-5.13 number fields fixed sage-5.13.beta0 Jeroen Demeyer John Cremona N/A #14476, #15124
