Thanks, this is helpful. I've pushed your patch and made a few style fixes:

For future reference, you can use the three-argument calling form of
assert for testing relative instead of absolute tolerance (pass a
negative argument there). This is helpful because it produces a better
diagnostic if the assertion fails.

I also changed to xtest the two tests that failed on my machine. One
of them seems to be getting the signs wrong for some entries. The
other one seems to be getting the precision wrong.
