Question

SELECT CAST (330/60 AS FLOAT) AS result

or

SELECT CONVERT(FLOAT, 330/60) AS result

Actually I am expecting result as 5.5

But it is returning 5. Why?

And tell me any solution to get result as 5.5

Answer 1

Use 60.0 to force fixed-point types:

 SELECT CAST (330/60.0 AS FLOAT) AS result
 SELECT CONVERT(FLOAT, 330/60.0) AS result

The calculation of 330/60 is done as integers which will round the result. After that you cast to float. You can use a numeric type right from the beginnging and don’t need to cast:

SELECT 330/60.0 AS result
