There's a function in SQL Server called ROUND():-

Quick suggestion, use the round function and set the third parameter to 0.

😎

Example

SELECT 34.100 AS IN_VAL,ROUND(34.100,0,0) AS OUT_VAL UNION ALL

SELECT 39.8 AS IN_VAL,ROUND(39.8,0,0) UNION ALL

SELECT 35.4 AS IN_VAL,ROUND(35.4,0,0)

Results

IN_VAL OUT_VAL

------- --------

34.100 34.000

39.800 40.000

35.400 35.000

That should do it

;

WITH

CTE AS

(

SELECT CAST(ROUND(VAL,0,0) AS VARCHAR(10)) AS VAL

FROM 'YOURTABLE'

)

SELECT SUBSTRING(VAL,1,2) + '%' AS NDM$

FROM CTE

LEFT(CAST(ROUND([Val],0,0) as nvarchar(10)),2) + '%' AS [val]

to get the results some like this

34.100 34.000 ->34%

39.800 40.000 ->40%

35.400 35.000 ->35%

But this does not holds good when the percentage is 100% this holds when the percentage two characters. Can any body guide how to solve this

The best way to solve this is leave the formatting to the front end. You should pass numeric values in this case to the front end. There the % can be added. If you turn everything into formatted strings the front end can't accurately sort or do any types of calculations without first removing the formatting.

--EDIT--

And why would you use nvarchar? Last time I checked all values for numbers will fit easily in the standard ASCII set so no need for the extended characters here.
