An (ir)rationals library for python.
(This library is a work in progress, and currently unfinished.)
import the rationals type:
from irrat import *
and then use rationals:
r = rat(22, 7)
r2 = rat(-153, 517)
r3 = r + r2
print(r3 > 0.5)
They are designed to delay computation until you ask for it (e.g. via comparison.)
Still some stuff to do, they will try to completely resolve addition and subtraction, I need to find a way to delay that using new Expression types.
Another big TODO is computing the decimal number string representation to arbitrary precision.
Finally, we eventually want to add the irrat type, which can handle sqrt, PI, e, and other irrational and transcendental numbers inside the expressions.
