The quadratic-irrational package
- 'ghc-options: -O2' is rarely needed. Check that it is giving a real benefit and not just imposing longer compile times on your users.
A quadratic irrational is a number that can be expressed in the form
(a + b √c) / d
where a, b and 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 some quadratic equations – the quadratic formula has a familiar shape.
A continued fraction is a number that can be expressed in the form
a + 1/(b + 1/(c + 1/(d + 1/(e + …))))
alternatively expressed using the notation
[a; b, c, d, e, …]
where a is an integer and b, c, d, e, … are positive integers.
Every finite continued fraction represents a rational number and every infinite, periodic continued fraction represents a quadratic irrational.
3.5 = [3; 2] (1+√5)/2 = [1; 1, 1, 1, …] √2 = [1; 2, 2, 2, …]
