[Numpy-discussion] math.fsum() like ufunc for numpy

[Daniele Nicolodi]

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 straightforward to implement. I can try to submit a
patch for it.

Cheers,
Daniele
