[Numpy-discussion] Importance of order when summing values in anarray
Tue Dec 9 09:00:07 CST 2008
Ahh, but I would have thought the precision for the array operation would be
the same no matter which values I wish to sum? The array is in float64 in
I would not have thought altering the type of the integer values would make
any difference as these indices are all below 5 milllion.
Perhaps I have misunderstood your suggestion could you expand.
Also, increase the numerical precision as that may depend on your
