You probably run a 32 bit OS. IEEE extended precision is 80 bits. On 32 bit
systems it
On my two systems with Intel Core2 DUO, finfo(float128) gives me the nameerro,
"NameError: name 'float128' is not defined". Why?

float128 should be 128 bits wide. If it's not on your platform, please
let us know as that is a bug in you

Hi Bruce,
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
all cases.
I would not have thought altering the type of the integer values would make
any difference as these indices are all below 5 m

נושא: [Numpy-discussion] Importance of order when summing values in anarray
Hi All,
I have encountered a puzzling issue and I am not certain if this is a
mistake of my own doing or not. Would someone kindly just look over this
issue to make sure I'm not doing something very
