Synopsis
#include <flint/arb_hypgeom.h>void _arb_hypgeom_gamma_upper_fmpq_inf_bsplit(arb_t res, const fmpq_t a, const arb_t z, slong N, slong prec)sourceSets res to the asymptotic series of \Gamma(a,z) at infinity, including the prefactor z^{a-1} e^{-z}, truncated before the term of index N and computed by binary splitting. The truncation error is not included.
