acb_contains_interior

Synopsis#include <flint/acb.h>
int acb_contains_interior(const acb_t x, const acb_t y)source

Returns whether y is contained in the interior of x.

The interior is that of the rectangle in the plane, so the test is always false if x has an exact real or imaginary part: an imaginary part 0 is not in the interior of the point interval 0. In particular it is false for two real numbers. Such cases must be handled separately where a different interpretation is intended.
