Such number $x$ statistifies $i^x=x$. This can be solved with Lambert W function. Doing so, gives: $$x \approx -1.861743075013160441612498412-0.4107999688363923527986399873 i$$ $$x \approx 0.4382829367270321593816295045+0.3605924718713854895879688663 i$$ But we see that they are always positive, so it is the second one.
