Synopsis
#include <flint/arb_hypgeom.h>slong _arb_hypgeom_gamma_upper_fmpq_inf_choose_N(mag_t err, const fmpq_t a, const arb_t z, const mag_t abs_tol)sourceReturns a number of terms N of the asymptotic series of \Gamma(a, z) at infinity that gives an absolute error at most abs_tol, and sets err to a bound for the truncation error. Returns -1 if the tolerance cannot be reached. Assumes z > 0.
