Sorry, here's the code:
CREATE TABLE table2 (
"s_val" NUMERIC(6,2),
"e_val" NUMERIC(6,2)
);
CREATE FUNCTION divide () RETURNS numeric AS
$body$
declare
retval numeric(6,2);
rec record;
begin
SELECT * INTO rec FROM test.table2 LIMIT 0;
rec.s_val = 100.0;
rec.e_val = 101.0;
-- returns correct value w/ casting:
--retval = ((rec.s_val::numeric(6,2) - rec.e_val::numeric(6,2)) /
rec.s_val::numeric(6,2)) * 100;
-- returns incorrect value, as if fields have invalid datatypes:
retval = ((rec.s_val - rec.e_val) / rec.s_val) * 100;
return retval;
end
$body$
LANGUAGE 'plpgsql';
