What is the computational complexity of a hypothetical
float.as_simplest_integer_ratio() method?  How hard that is to find is not
obvious to me (probably it should be, but I'm not sure).

Keeping medicines from the bloodstreams of the sick; food
from the bellies of the hungry; books from the hands of the
uneducated; technology from the underdeveloped; and putting
advocates of freedom in prisons.  Intellectual property is
to the 21st century what the slave trade was to the 16th.
