Noun[edit]
continued fraction (plural continued fractions)
 (mathematics, number theory) A compound numerical expression consisting of an integer plus a fraction whose numerator is a positive integer and whose denominator is a continued fraction (an integer plus a fraction), and so on, with finite or infinite recursion.

 Several results focus on the famous Rogers–Ramanujan continued fraction [47], [48, pp. 214215], the only continued fraction appearing in Ramanujan's published papers.

 We achieve this by using wellknown examples from the number theory pertaining to the continued fractions. Any sequence of natural numbers drawn from the probability distribution of the quotients of the continued fraction corresponding to an irrational number represents a typical sequence, in the sense that almost all sequences of quotients have this distribution.

 We have seen that all rational numbers, and no other number, can be expressed as finite simple continued fractions.
 The main reason of interest of continued fractions, however, is in their application to the representation of irrational numbers. To that end we shall need infinite simple continued fractions.

Usage notes[edit]
The initial integer may be zero or even negative; subsequent nonnumerator terms should be positive (while not strictly necessary, it is easier to prove convergence with positive terms).
Generally, it is assumed that every numerator is 1; if distinction is necessary, such a fraction may be called regular or simple or be said to be in canonical form. (See continued fraction on Wikipedia.Wikipedia )
