In this article, we’ll develop a Haskell library for continued fractions. Continued fractions are a different representation for real numbers, besides the fractions and decimals we all learned about in grade school. In the process, we’ll build correct and performant software using ideas that are central to the Haskell programming language community: equational reasoning, property testing, and term rewriting.
