Continued fraction

Uncommon card · No. 149593

A continued fraction is a mathematical expression written as a fraction whose denominator contains a sum involving another fraction, which may itself be a simple or a continued fraction. If this iteration (repetitive process) terminates with a simple fraction, the result is a finite continued fraction; if it continues indefinitely, the result is an infinite continued fraction. The special case in which all numerators { a i } {\displaystyle \{a_{i}\}} (see image) are equal to one, and all denominators { b i } {\displaystyle \{b_{i}\}} are positive integers, is referred to as a simple (or regular) continued fraction. Any positive rational number can be expressed as a finite simple continued fraction, and any positive irrational number can be expressed as an infinite...
