What is Continued fraction?
[[File:Schwenter - Deliciae physico-mathematicae oder Mathemat. und philosophische Erquickstunden, 1636 - 4696404.tif|thumb|Daniel Schwentner - Deliciae physico-mathematicae (1636)]] A '''continued fraction''' is a concept from [[mathematics]] and [[number theory]]. It is written as an integer, plus a [[Fraction (mathematics)|fraction]]. The numerator of the fraction, is again an integer, and for the denominator, the rule repeats. Every [[real number]] can be expressed as a continued fraction. While it is possible to use continued fractions for calculations, they are used to find [[Approximation|approximations]] for [[Irrational number|irrational numbers]]. [[Leonhard Euler]] and [[Joseph-Louis Lagrange]] first formalized the concept, even though it was used before. [[Category:Number theory]] [[Category:Fractions (mathematics)]]
