Continued fraction library

Project description

.. include:: <isogrk1.txt>


Continued is a simple library for representing and operating on numbers
represented as continued fractions.


* Conversion from a plethora of representations to continued fractions

* int
* float
* decimal.Decimal
* fractions.Fraction and numbers.Rational

* Basic arithmetic: addition, subtraction, multiplication, division
* Popular irrational and transcendental identities, to arbitrary (infinite)

* *e* (Euler's number)
* |pgr|
* |phgr| (the Golden Ratio)

* Arbitrary-precision quadratic surds



- sqrt(2) * sqrt(2) goes into an infinite loop, as does any other operation
with an arbitrary string of 0.

Some enhancements are planned.

- Surds should permit the form (a + sqrt(b))/c without an extra pair of
combination generators.
- Trigonometric operators.
- Radix-based decoding.



Initial release.
