SQL - truncating to two decimal places

This query produces stuff like

      Round( (SUM(Field1 * 100) / Field2, 2) AS MktPct
FROM Table


How would i get rid of the extra zeros after the decimal point?

How about:

      CAST(Round( (SUM(Field1 * 100) / Field2, 2) as decimal(18,2)) AS MktPct
FROM Table

(Adjust the 18 to fit how many significant digits you need)

Assuming you wouldn't want any non-needed zero (even if it's even in the first or second places after the decimal):

      CONVERT(float, Round( (SUM(Field1 * 100) / Field2, 2)) AS MktPct
FROM Table
Kyle AbrahamsSenior .Net DeveloperCommented:
select CAST (SUM(Field1 * 100) / field2 as numeric(18,2))

cast automatically rounds.

I think that is right.

I don't understand the following quote .. could you give me an example of what could go wrong?

"Assuming you wouldn't want any non-needed zero (even if it's even in the first or second places after the decimal):"
Steve WalesSenior Database AdministratorCommented:
I think he means if you have 151.00. Do you want it to display as 151.00 or 151.

Actually, I wrote that before re-reading your heading. You want two decimal places, and I answered as if you would want things like 1.1000000 to look like 1.1 rather than 1.10. The other guys have given you better solutions if you want the cents (2 decimal places) to show. They deserve the points.

You can save the use of FLOAT for something else in the future. :)

this is working with the  CONVERT(float,Round( (SUM(t1.[Market Value]) * 100) / TotMktValue, 2, 2)) AS MktPct

How would i change it to use cast ... i keep messing up the syntax...
Steve WalesSenior Database AdministratorCommented:
My response and Kyle's both give you that syntax.  If it is not work, please post the error you are getting
