Some more example for the integral: Integrate[PolyLog[2, Exp[I*(x - y)]], {y, 0, 2*Pi}] with x=5/2, I get 0 as expected. But with x=2.5 I get 19.634954084936204 + I*1.7763568394002505`*^-15 which is not close to zero! With x=-2.5 I get 44.964016795241896 + I*1.7763568394002505`*^-15 etc. I have only one conclusion: there is a bug with Integrate or PolyLog or both. Any suggestion? D.
