 The `continuedfractions` package is aimed at users interested in:
 
 * working with (finite, simple) continued fractions as Python objects, in an intuitive object-oriented way
 - making stateful computations involving key properties such as elements/coefficients, convergents, semiconvergents, remainders, and others
 * operating on them as rationals and instances of the [`fractions.Fraction`](https://docs.python.org/3/library/fractions.html#fractions.Fraction) standard library class
 * testing approximations for irrational numbers
 * exploring other related objects such as rational points in the plane, enumerations of rational numbers, mediants, and special sequences of rational numbers such as Farey sequences

+The [documentation](continuedfractions.readthedocs.io) provides more detailed information on aspects of the package libraries and their implementation.
