FORMULA
1/(-1+1/(-1+exp(-1/2*log(abs(-1+exp(-1/3*log(abs(-1+exp(-1/4*log(abs(-1+exp(-1/5*...)...)
= x_1 where x_n = 1/(x_{n+1}^(1/n) - 1).
EXAMPLE
1 + 1/( 5 + 1/( 2 + 1/( 1 + 1/( 81 + 1/( 3 + 1/( 2 + 1/( 2 + 1/( 1 + 1/( 1 + ... )...) = 1.1874523511265010545954801583965193512156926815858603530101041261990...
