Hi,
I am getting strange results from the sum function as follows:
corp=# select amount from acc_trans where trans_id=19721 and chart_id=10019;
amount
---------
4.88
117.1
-121.98
(3 rows)
corp=# select sum(amount) from acc_trans where trans_id=19721 and
chart_id=10019;
sum
----------------------
-1.4210854715202e-14
(1 row)
amount is defined as double precision. I noticed that if I cast amount
as numeric, the sum comes out 0 as expected.
I am using postgresql 8.0.1
Thanks in advance for any help or suggestions.
