Matt Juntunen commented on GEOMETRY-143:
----------------------------------------
I've been looking at this for the past couple of days and I believe the issue
is deeper than just this one case. The behavior of {{CutAngle.classify}} is not
well defined in general with input values close to zero. I'm using the
submitted patch as a starting point, adding additional unit tests, and trying
to settle on an implementation. I hope to have a PR ready for review soon.
> AngularInterval missclassify max boundary at 2pi- as outside

> Key: GEOMETRY-143

>
> When a AngularInterval has maxBoundary smaller than 2pi and equivalent to 2pi
> within precision, then the interval has false wrapZero but the upper boundary
> is classified by minBoundary as positive. as a result the point is classified
> as outside the interval instead of on the boundary.
> can be confirmed with the test:
> checkInterval(AngularInterval.of(6,Double.parseDouble("0x1.921fb54442c8ep2"),TEST_PRECISION),6,Double.parseDouble("0x1.921fb54442c8ep2"));
