I have an array of number field elements: sage: [x for x in bounds] [4*x - 1, 10/3*x - 4/3, 4*x - 1, 2*x - 1, 4*x - 1, 4*x - 1, 0]
They belong to a field that has an embedding, and I would like to sort them according to their real values. I can do it using float conversions: sage: sorted(float(x) for x in bounds) [-0.26794919243112281, -0.11324865405187112, 0.0, 0.46410161513775439, 0.46410161513775439, 0.46410161513775439, 0.46410161513775439] Or: sage: sorted(bounds, key = lambda x: float(x)) [2*x - 1, 10/3*x - 4/3, 0, 4*x - 1, 4*x - 1, 4*x - 1, 4*x - 1] But, this is a bit messy, and could be imprecise. It would be good if I could just do: sage: sorted(bounds) [4*x - 1, 10/3*x - 4/3, 4*x - 1, 2*x - 1, 4*x - 1, 4*x - 1, 0] But this doesn't appear to work! Is there a way to do this?
