Comment (by dimpase):
Replying to [comment:2 mkoeppe]:
> I'm a bit puzzled why you would want doctests for the particular
floating point noise that you get from this version of the solver. Seems
like extra work every time the package is upgraded?
I tried to round things using '...' etc as much as possible. I can in
principle go
further with replacing things like
{{{
sage: (p.slack(0)*p.dual_variable(0)).trace()
1.71...e-07
}}}
by
{{{
sage: 0.0e0 <= (p.slack(0)*p.dual_variable(0)).trace() < 1.75e-07
True
}}}
Eventually we should think how to adapt your testing framework to SDP.
