How to change a decimal to a nearest whole number in MySql ?

To change a decimal to the nearest whole number in MySQL, you can use the ROUND() function or the CEIL() function you can also use FLOOR() function.

How to use CEIL() function on mysql: The CEIL() function in MySQL is used to round up a decimal number to the nearest whole number

For example:

SELECT CEIL(3.14);

This will return 4, as 4 is the smallest integer that is greater than or equal to 3.14

It can also be used in more complex expressions when you need on your project:

SELECT CEIL(9/3);
