void acb_dirichlet_gram_point(arb_t res, const fmpz_t n, const dirichlet_group_t G, const dirichlet_char_t chi, slong prec)source

Sets res to the n-th Gram point g_n, the unique solution in [7, \infty) of \theta(g_n) = \pi n, for n \ge -1. Only the Riemann zeta function is supported: G and chi must be NULL; otherwise, or for n < -1, the result is indeterminate.
