In this section of the miscellaneous mathematics category the focus is Continued Fractions. The purpose of this page is among others to provide fundamental facts about the subject with accompanying examples.

Continued Fractions and semiconvergents as approximations to rational numbers. There are several sources expanding the approximation theme and not so many about semi-convergents, and they are mostly without proofs. This note with proofs in short style is intended to cover a part of the subject.
