Hi,
I have found the following strangeness on Windows versions:
create table round_test (id int primary key, value double precision);
insert into round_test(id, value) values(1, 1.5);
insert into round_test(id, value) values(2, -1.5);
insert into round_test(id, value) values(3, 3.5);
select round(value) from round_test;
psql 8.2.13 returns
2
-2
4
But psql 8.3.3 returns
1
-1
3
Trying more values it seems that 8.2 rounding works according to banker's rounding rules.
Can you confirm this?
How can I avoid this incompatibility or perhaps bug?
Thanks,
Otto
