Synopsis#include <flint/arb.h>
void arb_euler_number_fmpz(arb_t res, const fmpz_t n, slong prec)source
void arb_euler_number_ui(arb_t res, ulong n, slong prec)source

Set res to the Euler number E_n, defined by the exponential generating function 1/\cosh x. The result is exact if E_n fits in prec bits.
