Converting Sp Outcome

Hi all,

i have an stored procedure that returns a value, i want to convert that value into smallmoney, is this possible and i yes how?

here is my code:

CREATE proc CP_avgloss_total
@mID varchar(10),
@startdate datetime,
@enddate datetime

as
select

case

((sum(playtime))/ 3600)
when 0
then 0
else ((sum(vtp)-(sum(moneyout)))/100) / ((sum(playtime))/ 3600)
end avgloss
from dbo.total
where
machineID = @mID
and convert(varchar,njdate,121)
between convert(varchar,@startdate,121)
and convert(varchar,@enddate,121)

GO

The value that needs to convert is avgloss

Hope someone can help me with this.
Cheers Wim
