quadratic-irrational: An implementation of quadratic irrationals
A quadratic irrational is a number that can be expressed in the form
(a + b √c) / d
d are integers and
c is a square-free natural number.
Some examples of such numbers are
(1 + √5)/2(the golden ratio),
solutions to quadratic equations with rational constants – the quadratic formula has a familiar shape.
A simple continued fraction is a number expressed in the form
a + 1/(b + 1/(c + 1/(d + 1/(e + …))))
or alternatively written as
[a; b, c, d, e, …]
a is an integer and
e, … are positive integers.
Every finite SCF represents a rational number and every infinite, periodic SCF represents a quadratic irrational.
3.5 = [3; 2] (1+√5)/2 = [1; 1, 1, 1, …] √2 = [1; 2, 2, 2, …]
