Re: [sage-devel] Re: hyperbolic_polygon bug

Let me advertize that sage-flatsurf (https://github.com/flatsurf/sage-flatsurf) has an implementation of the hyperbolic plane with exact coordinates The following code ``` from flatsurf import HyperbolicPlane H = HyperbolicPlane(AA) z0 = H.point(2*AA(2).sqrt()/3 - 1, 4/6, model='half_plane') z1 =

[sage-devel] Re: hyperbolic_polygon bug

This was previously reported as issue #32362 on github , so any further discussion should take place there. The solution suggested there is to have sagemath calculate endpoints in the Poincare disk model, instead of in the upper half plane model.
