How to force numeric evaluation?

I need to evaluate the PolyLog function at some points, but I'm interested in numeric values. E.g. PolyLog[3, 2.7] works fine, but PolyLog[3, e] just prints the same PolyLog[3, e] . I somehow need to convert this symbolic representation to a number. Seems like a simple question, but I couldn't find the answer.

$\begingroup$ 
N@PolyLog[3,e] or N[PolyLog[3,e]]

Also if by e you mean E or Exp[1] (Mathematica's notation), then you'll have to change that.
