Hello,
   
I'm trying to get a value with 1 digit precision when I do the below calculation:
((636/80)/3)


I tried casting the numerator as DECIMAL, but I get a final result with 8 decimal places as shown below.

SELECT (CAST(636 AS DECIMAL(18,2))/80)/3
Result: 2.65000000

But I want only 1 decimal place in the result as 2.7

How do I achieve this?

Thanks!

try this perhaps?
SELECT
  (636.0/80)/3
, (636/80.0)/3
, (636/80.0)/3.0
, ROUND( (636.0/80)/3 , 1) -- shows as 2.7
, ROUND( (636/80.0)/3 , 1) -- shows as 2.7
, ROUND( (636/80.0)/3.0 , 1) -- shows as 2.7
	
results of this:

| COLUMN_0 | COLUMN_1 | COLUMN_2 | COLUMN_3 | COLUMN_4 | COLUMN_5 |
|----------|----------|----------|----------|----------|----------|
|     2.65 |     2.65 |     2.65 |      2.7 |      2.7 |      2.7 |
