Synopsis#include <flint/acb.h>

void acb_lambertw_asymp(acb_t res, const acb_t z, const fmpz_t k, slong L, slong M, slong prec)source

Sets res to W_k(z) computed from L and M terms of the bivariate asymptotic series at 0 or \infty. The formula is valid everywhere, but the error bound is finite only when |\log z| is large enough.
