With same version except for Mac OS X 10.9 (on machine with 16GB RAM), also no
problem getting +/ i. 10E8, but +/ i. 10E9 caused OS to run out of memory.
By contrast, on same machine, with Mathematica 9.0.1 (where indexing origin is
1, not 0):
Total[Range[10^9 - 1]]
499999999500000000
Total[Range[10^10 - 1]]
(crashes OS with out-of-memory)
(* another way: *)
Sum[i, {i, 10^10 - 1}]
49999999995000000000
There was no real point with Mathematica trying to go to higher orders of
magnitude, since Mathematica can do this symbolically:
Sum[i, {i, 10^n - 1}]
2^(-1 + n)*5^n*(-1 + 10^n)
