T-SQL Round to decimal places

Question

How do I round the result of matchpercent to two decimal places (%)? I\'m using the following to return some results:

DECLARE @topRank int
set @topRank=(SELE         


        

Answer 1

CAST/CONVERT the result:

CAST((CAST(ftt.RANK as DECIMAL)/@topRank) AS DECIMAL(n,2)) as matchpercent,

...where n is a number large enough not to truncate left of the decimal point. That is to say, if you use "123.456", you need to use DECIMAL(7,2) because the total length is 7 digits.
