Simple continued fraction

Builds on Continued fraction

Definition

A simple continued fraction is a continued fraction whose partial numerators are all 11. Its first term a0a_0 is an integer, and its later terms a1,a2,…a_1, a_2, \dots are positive integers: [a0;a1,a2,… ]=a0+1a1+1a2+⋯[a_0; a_1, a_2, \dots] = a_0 + \cfrac{1}{a_1 + \cfrac{1}{a_2 + \cdots}} The sequence of terms can be finite or infinite.

Remarks

The ana_n are called the partial quotients. For example, [2;3,4]=2+13+1/4=3013[2; 3, 4] = 2 + \frac{1}{3 + 1/4} = \frac{30}{13}. An infinite simple continued fraction always converges, by the convergence of the convergents. Each real number has a continued fraction expansion of this form.
