Comment (by jhonrubia6):
I've also modified the doctoring in {{{_to_std_geod()}}} method since it
randomly failed (depending on the random UHP points, for example:
{{{
sage: UHP = HyperbolicPlane().UHP()
sage: p1=0.869685163129173 + 0.897487924526729*I
sage: p2=5.71917016919078 + 7.09666543326670*I
sage: g = UHP.get_geodesic(p1, p2)
sage: p= g.midpoint().coordinates()
sage: A = g._to_std_geod(p);A # Send midpoint to I.
sage: A = UHP.get_isometry(A)
sage: [s, e]= g.complete().endpoints();s;e;p
sage: bool(abs(A(s).coordinates()) < 10**-9)
True
sage: bool(abs(A(g.midpoint()).coordinates() - I) < 10**-9)
True
sage: bool(A(e).coordinates() == infinity)
False
sage: bool(abs(A(e).coordinates())>10**9)
True
}}}
