Though it is hard to resist Thierry Dumont's invitation to a large cup of coffee, my inclination would be to compile an MPFR program for calculations of this sort. Incidentally, range(-10000,10000) is not symmetric about 0. In fact, there's no need for negative indices at all in this particular sum.
