Comment(by GeorgSWeber):
The file "devel/sage/sage/rings/number_field/totallyreal_rel.py" has five
functions, and only three of these have doctests. The problem in this
ticket is with one these, which is an internal function not used
elsewhere. From what I guess from the code, it is meant to be called with
"inexact" bounds --- see the use of "eps_global".
So we might "heal" this internal function by using some kind of interval
technique --- but the price could be high, i.e. slowing down the algorithm
where this internal function is intended to be used.
I rather propose to heal the doctest by giving bounds [-0.1, 5.1] ...
instead of [0, 5] ..., which most probably is far closer to the actual
intended usage than the current doctest.
