Hello,
there would be interest in adding a floating point accurate summation
function like Python's math.fsum() in the form of an ufunc to NumPy?
I had a look at the algorithm
(http://code.activestate.com/recipes/393090-binary-floating-point-summation-accurate-to-full-p/)
and it looks quite
I think that would be great. Technically what you'd want is a gufunc.

related this PR attempts to improve the accuracy of summation:
https://github.com/numpy/numpy/pull/3685
but math.fsum gives the exact result so it would a valuable ufunc even
when that PR is merged.
python3.4 will have yet another accurate summation in the statistics module:
