We can use MySQL ceil() function to get the smallest integer which is higher than the input value.
Same way we can use the floor function to get the highest integer which is lower than the input value.
Here are some examples of ceil function.
select ceil(5.94) => 6
select ceil(5.24) => 6
select ceil(-5.24)=> -5
select ceil(-5.54) => -5
We can use ceil function to our student table where we will calculate the average mark of the students.
SELECT avg(mark) as avg FROM `student`
Output = 74.6571
Now we can use ceil command like this.
SELECT ceil(avg(mark)) as avg FROM `student`
Output = 75
