SQL error 'Unable to identify an operator = for type numeric?'

I have table defined as such:

Create Table t1
(
f1 int,
f2 numeric (13,2)
)

insert into t1 values (1,12.22);
insert into t1 values (2,12);

if I do the following query I receive data:

Select  * from t1 where f2 = 12;

If I do the following I get
Unablel to identify an operator '=' for types 'numeric' and 'double
precision'  You will have to retype this query using an
explicit cast:

Select  * from t1 where f2 = 12.22;

If I put single quotes around '12.22' it works.  I must be using the wrong
data type

What data type do I need to set instead of MONEY?  Should I use FLOAT8?
