I am new to Postgres and have an embarassingly simple question. I am
v8.2 on Windows Vista although I don't think that has any bearing on the


create table test (col1 int, col2 int)
insert into test values (1,2);
select col1/col2 from test....yields 0 not 0.5 - why?

Presumably this is because both col1 and col2 are ints and the output
to be casted somehow? Or is it because PGAdmin's SQL interface does not
default show the decimal places of output?

Appreciate your help.
