Comment #2 on issue 2723 by asmeurer: What should summation() do with non-integer limits?
http://code.google.com/p/sympy/issues/detail?id=2723
Sorry, I got the variables backwards in your example. What you should do instead is:
In [12]: print summation(exp((x - 0.5)*a), (x, 0, 1)) exp(0.5*a) + exp(-0.5*a) -- You received this message because you are subscribed to the Google Groups "sympy-issues" group.
