Synopsis#include <flint/decimal.h>
void decball_init(decball_t res, gr_ctx_t ctx)source
void decball_clear(decball_t res, gr_ctx_t ctx)source
void decball_swap(decball_t x, decball_t y, gr_ctx_t ctx)source
void decball_set_shallow(decball_t res, const decball_t x, gr_ctx_t ctx)source
int _decball_is_exact(const decball_t x, gr_ctx_t ctx)source
int _decball_is_finite(const decball_t x, gr_ctx_t ctx)source

Memory management, as for decfloat_init, and tests whether the radius is zero, respectively whether the ball is finite.
