Round function used to round the number to the nearest while trunc used to truncate delete the number from some position.
Difference between round and floor in sql.
1 3 1 1 5 2 round a1 0 floor rounds always down e g.
If d is 0 then the decimal point is removed.
Round rounds down or up e g.
Difference between trunc and round functions oracle.
Floor evaluates the value on the right side of the decimal and returns the largest integer less than or equal to the specified numeric expression and accepts one value.
Rounddown 1 61 1 1 6.
Sql server round ceiling and floor examples for integer data types.

Meanwhile round will round number that has decimal value lower than 0 5 to lower int and when more than 0 5 to higher int.
But while round returns the same scale where possible as the data type passed in the data type floor returns has a 0 scale where possible.
1 61 1 7 ceiling a1 0 1 not sure if they exist already in 2007 usinig 2010 there is now also a roundup rounddown.
The truncate function is used to return the value of x truncated to d number of decimal places.
Difference between floor ceiling and round.
Consider the following example.
So floor 1 2 1 and floor 1 9 1.
Oddly round x 0 1 returns almost the same value as floor.
Sql home sql intro sql syntax sql select sql select distinct sql where sql and or not sql order by sql insert into sql null values sql update sql delete sql select top sql min and max sql count avg sum sql like sql wildcards sql in sql between sql aliases sql joins sql inner join sql left join sql right join sql full join sql self join sql.
We do not have any decimal digit.
So round 1 2 1 but round 1 9 2.
In the output we can see that all three sql rounding functions round ceiling and floor return the same output for the positive integer value.
Similarly ceiling and floor function also do not return the smallest or largest integer value.
1 61 1 6 floor a1 0 1 ceiling rounds always up eg.
Round returns n rounded to i places to the right of the decimal point.
Therefore round function does not round the value.
Floor returns the integer value less than or equal to the value passed in.
With this post i am trying to provide bit of explanation and some examples of round trunc ceil and floor functions in oracle database.
In sql queries sometimes we need to round off some decimal or float values at that time we always think that which option to be applied while we have three different kinds of system defined sql rounding functions ceiling floor and round.
Some cases both returns same result.
Trunc and round function looks similar but not exactly.
Floor will simply drop decimal value and return only integer.
Very similar to round x 0 1.
