%N Decimal expansion of the real part of the root of the function x^y = y.

%C This value is negative.

%C It is not known if this number has a closed form.

%C This root occurs on the real component of the function x^y = y for x values which are all real.

%F Original fixed point function is of the form: x^y = y. When solved for y: y = -ProductLog(-log(x))/log(x).
