Description (last modified by slelievre)

We decided to fix the underlying sign error in #29936. So this is a duplicate.

In src/sage/geometry/hyperbolic_space/, four doctests claim to be precise up to 1e-9 for random geodesics.

Unfortunately, this assumes set_random_seed(0) and the claim fails by far for many "random" values. In #29936 we specified the precision for which this does hold, which is not much. This should be fixed.
