How can I round a value in SQL, used round function .actual result is 555.81 getting 555 script is round(expression,0)

this is the result which I used round(expression,2) when I use round(expression,0) getting 555 as answer

Answer 1

ROUND documentation on MSDN

select
  [raw]       = 555.81, 
  [rounded]   = round(555.81, 0),
  [truncated] = round(555.81, 0, 1)

Result:

|    raw | rounded | truncated |
|--------|---------|-----------|
| 555.81 |     556 |       555 |

Answer 2

I believe it is rounding down. round(expression+0.5,0) Should work but I have not tested it.
