polyroots should give full accuracy unless there are repeated roots. > Indeed it's strange that the imaginary parts don't vanish, even if you > use higher precision for evaluating.

It should work if you pass myEqConstants.n(50) instead of myEqConstants as input. I think it assumes that the input is only 15-digit accurate.
