The problem is is that he doesn't have a float. He has one of our float64scalar
objects. The str() of a real Python float will give as many digits as are
necessary to recreate number and no more (or maybe one or two more). A str() of
a float64scalar will round according to some rule that I haven't figured out,
yet. It doesn't seem to be configurable with numpy.set_printoptions().

that is made terrible by our own mad attempt to interpret it as though it had
an underlying truth."
