void _arb_hypgeom_gamma_upper_fmpq_inf_bsplit(arb_t res, const fmpq_t a, const arb_t z, slong N, slong prec)source

Sets 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.
