Complex factorial, gamma and lngamma functions
Is there (maybe) an issue with the complex factorial, gamma and lngamma function in WP34S?
WP34S emulator: (-6.2-7.6i)! = -20.3658 + i1.2046
WolframAlpha: (-6.2-i7.6)! = -9.8594e-11 + i3.2965e-12
Curiously the results for (6.2+7.6i)! are the same.
Are both results correct? I'm really not used to this complex functions.
By the way for the gamma and lngamma functions the results are also divergent.
