%N A364356 Decimal expansion of negative value of function Gamma(-A364355 + i*sqrt(1-A364355^2)).
%C A364356 Only for x = A364355 = 0.54197987169489060244332278779... the Gamma(-x + i*sqrt(1-x^2)) is a real number and -1 < x < 1 (for one case is an imaginary number see A364821 and for other values x is a complex number).
%e A364356 Gamma(-A364355 + i*sqrt(1-A364355^2)) = -0.6749332470449905963531...
