radix_integer_inv, radix_integer_is_invertible
Synopsis
#include <flint/radix.h>int radix_integer_inv(radix_integer_t res, const radix_integer_t x, const radix_t radix)sourceint radix_integer_is_invertible(const radix_integer_t x, const radix_t radix)sourcex is invertible in \mathbb{Z} if and only if x = \pm 1. radix_integer_inv sets res to 1/x = x and returns 1 in that case and returns 0 otherwise.
