Or as part of the doctest "normalize" G.round(6): multiply by -1 if the

maybe it should be moved to a TESTS block instead of an EXAMPLES block.
I wonder what part of the algorithm leads to a difference choice of sign
on this one platform.
so something like:
sage: G.round(6)*sgn(G[0,0].real())
Thanks,

These are quite ugly solutions. How do people feel about having a
solution analogous to #10952?

For example, let "# sign variation" ignore every +, -, and space in the
output string.
