%N Decimal expansion of self-generating continued fraction with first term sqrt(2).

%C For x > 0, define c(x,0) = x and c(x,n) = [c(x,0), ..., c(x,n-1)]. We call f(x) the self-generating continued fraction with first term x. See A229779.

%e f(sqrt(2)) = 1.967552445870374625939484944608025225084419714910878...
