If d is negative then d number of values in the integer part of the value is truncated.
Difference between round and floor in sql.
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.
1 3 1 1 5 2 round a1 0 floor rounds always down e g.
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.
Round rounds down or up e g.
Floor returns the integer value less than or equal to the value passed in.
Floor will simply drop decimal value and return only integer.
Round function used to round the number to the nearest while trunc used to truncate delete the number from some position.

Rounddown 1 61 1 1 6.
Therefore round function does not round the value.
So floor 1 2 1 and floor 1 9 1.
Very similar to round x 0 1.
The argument i can be negative to round off digits left of the decimal point.
Let s walk through each function with a few different data types to see the results.
Trunc and round function looks similar but not exactly.
Default value of i is 0.
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.
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.
If d is 0 then the decimal point is removed.
Some cases both returns same result.
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.
Difference between trunc and round functions oracle.
Difference between floor ceiling and round.
Sql server round ceiling and floor examples for integer data types.
Similarly ceiling and floor function also do not return the smallest or largest integer value.
Oddly round x 0 1 returns almost the same value as floor.
We do not have any decimal digit.
So round 1 2 1 but round 1 9 2.
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.
Consider the following example.
