Synopsis#include <flint/acb.h>
void acb_agm1(acb_t m, const acb_t z, slong prec)source

Sets m to M(z) = \operatorname{agm}(1, z), defined by always choosing the optimal branch of the square root in the AGM iteration. M is continuous except for a branch cut on the negative real axis, where it is continuous from above.
