Synopsis#include <flint/acb_hypgeom.h>
void acb_hypgeom_bessel_j_0f1(acb_t res, const acb_t nu, const acb_t z, slong prec)source

Sets res to Jν(z)J_\nu(z) computed from the convergent series

Jν(z)=1Γ(ν+1)(z2)ν0F1(ν+1,−z24),J_{\nu}(z) = \frac{1}{\Gamma(\nu+1)} \left(\frac{z}{2}\right)^{\nu} {}_0F_1\left(\nu+1, -\frac{z^2}{4}\right),

using J−n(z)=(−1)nJn(z)J_{-n}(z) = (-1)^n J_n(z) for negative integer ν\nu.
