how to remove undesirable trailing zeros when using Cast as Decimal?

Question

I am using below statement in Microsoft SQL Select statement and the result i am getting is like "100.00000000000" however i would like it to be as "100.00".. ie Only two trailing zeros after period. Can some one tell what i am missing here and how to fix it

round(Cast(count(Case when Newuser = 1 then 'Yes' end)as decimal) / count(Totalusers),4)*100 as '% New Users''

Answer 1

This is a matter of representation as a string / varchar, right? I always use convert to numeric and round. So: CONVERT(NUMERIC(16,desired_nr_of_decimals), ROUND(decimal_value, desired_nr_of_decimals))
