Complex map of the $-0.9$th iteration of exponent, which is also $0.9$th iteration of logarithm;

$u+\mathrm i v= \exp^{-0.9}(x+\mathrm i y)=\ln^{0.9}(x+\mathrm i y)= \mathrm{tet}(-0.9+\mathrm{ate}(x+\mathrm i y))$

For the evaluation, the non-integer iterate of exponential is expressed through tetration tet and arctetration ate. The complex double implementations FSEXP and FSLOG are used in the C++ code below.
