Synopsis
#include <flint/dirichlet.h>int dirichlet_parity_ui(const dirichlet_group_t G, ulong a)sourceint dirichlet_parity_char(const dirichlet_group_t G, const dirichlet_char_t x)sourceReturn the parity \lambda \in \{0, 1\} of \chi_q(a, \cdot), defined by \chi(-1) = (-1)^\lambda: 0 for even and 1 for odd characters.
