ANN: Experimental Number Types (Integer, Rational, Floats)

[Scott David Daniels]

Would it be rude to point to the farey function I've thrown in the Python
Cookbook here?

I know I had a hard time figuring out how to go from floating point (or more
generally a value of any kind) to a rational approximation.  The function
above shows how to get there if you can do multiplication and comparison
reasonably efficiently.  You could even use it to go from some fairly
high-precision Rational to a lower-precision rational (say, from
Rational(333, 106) to Rational(22,7) for example).
