Title: tests and docs for round/signif functions

tests and documentation for #1254, as promised. Note that the docs aren't tested, as I don't have the systems installed to do so, but it looks OK via eyeball. Also note that there are round cases that should work in theory (like truncating a near-maximal float) that don't work in practice because of implementation details. I don't know whether we should care or not.
