If I query select round(sin(2.0*pi()*0.51)) I get "-0" as return but zero is unsigned. but: select sin(2.0*pi()*0.51) returns: -0.0627905195293133 and select round(-0.0627905195293133) returns: 0 (no sign) I used cast to work around it: select round(sin(2.0*pi()*0.51))::int -- Sent via pgsql-bugs mailing list (pgsql-bugs@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-bugs
