I am evaluating the following:
N[Gamma[3/2] PolyLog[3/2, -Exp[3]]]
I got the answer
-3.97699 + 1.26361*10^-16 I
the real part is correct, but the answer contains a very small imaginary part, probably due to rounding errors. Has anyone encountered similar problems before?
Seems to be rounding errors
In[65]:= Chop[N[Gamma[3/2] PolyLog[3/2, -Exp[3]]]]
Out[65]= -3.97699
