## What is ceil function in MySQL?

MySQL CEIL() Function The CEIL() function returns the smallest integer value that is bigger than or equal to a number. Note: This function is equal to the CEILING() function.

## What is difference between Ceil and floor function?

The ceil function returns the smallest integer value which is greater than or equal to the specified number, whereas the floor function returns the largest integer value which is less than or equal to the specified number. But the floor and ceiling of an integer remain the same.

**What is Ceil and floor in MySQL?**

MySQL FLOOR() Function The FLOOR() function returns the largest integer value that is smaller than or equal to a number. Note: Also look at the ROUND(), CEIL(), CEILING(), TRUNCATE(), and DIV functions.

### Why ceil function is used?

### What is the difference between ceil and round?

ceil() rounds the number up, and round() rounds correctly depending on the number. Similarly to ceil() , there is floor() , which always rounds down. round() rounds a float value to the nearest integer . If either of the two integers on either side are equal distance apart, the even number is picked.

**What is the difference between floor and round?**

ROUND() function rounds the number up or down depends upon the second argument D and number itself(digit after D decimal places >=5 or not). FLOOR() function rounds the number, towards zero, always down.

## How is ceil calculated?

## What is the difference between round and floor in MySQL?

**What is floor and ceil value?**

In mathematics and computer science, the floor function is the function that takes as input a real number x, and gives as output the greatest integer less than or equal to x, denoted floor(x) or ⌊x⌋. Similarly, the ceiling function maps x to the least integer greater than or equal to x, denoted ceil(x) or ⌈x⌉.

### How do you round off in MySQL?

ROUND() Function in MySQL. The ROUND() function in MySQL is used to round a number to a specified number of decimal places. If no specified number of decimal places is provided for round off, it rounds off the number to the nearest integer. X : The number which to be rounded.
