Well, of course they are rational numbers. The only question is whether 1.0
should be inexact or exact. While that is not specified in the PEP (which
was meant for Barry to assign me a PEP number primarily...), I think
the principle of least suprise would be to treat 1.0 as inexact.
(IOW, not to promise that (1.0/3.0)*3.0 == 1.0)
