Hi,

I'm trying to do some calculations with large integers (~10^23), and

need accrate numbers. The problem is that I seem to be getting

numerical inaccuracies with these numbers when compared to somethign

as simple as Windows Calcualtor. I wasn't sure which was the correct

number so started doingsome mod calculations as well and when compared

to another system SAS seems to give up eg

mod(129**11,49) = 0

mod(128**11,49) = 0

(I've repreogrammed this without the mod function and get the same

values)

Both accorging to SAS, PL/SQL gives more believeable results of 19 and

18 respectively.

If anyone could tell what level of accuracy and precission I can

expect from SAS (v8 windows and VMS), and if the mod function works at

with these large numbers.

TIA

Bryan
