Use the Integer field type for non-decimal numeric values where performance and table storage limitations are especially important.
Try this:

create cursor mycursor(gamename c(5),quantity n(10,2))
insert into mycursor values ('fdss',1)
insert into mycursor values ('ghrr',1)
insert into mycursor values ('gersd',1)
insert into mycursor values ('few',2)
select avg(quantity) from mycursor

>Help please!
>Why don't I get 1.25 in the following syntax:

create cursor mycursor(gamename c(5),quantity i)
>insert into mycursor values ('fdss',1)
>insert into mycursor values ('ghrr',1)
>insert into mycursor values ('gersd',1)
>insert into mycursor values ('few',2)
>select avg(quantity) from mycursor

>I get integer(1) not 1.25, why?
