Turns out the IEEE specification includes a "negative zero." Rounding and .zero_at() might do the trick.

Six such changes in the "negative zero" patch. Successful with one instance where I converted a -0.0 to 0.0.

Jeroen - could you easily test/review this on the two failing machines? If it works across three architectures, I'll then apply the same technique to #10795, #10837 with some confidence.

Thanks for your patience with this (exasperating) numerical work.

Rob
