%N Decimal expansion of the infinite Fibonacci word, interpreted as a binary expansion.

%C That is to say, take A003849 (the morphism 0 -> 01 and 1 -> 0 starting from a single 0) and interpret it as a decimal fraction with the decimal point at the very beginning.

%C Davison shows that this constant is transcendental. - _Charles R Greathouse IV_, Feb 28 2014
