ceil

The ceil() function returns the nearest positive or negative integer value greater than or equal to the provided decimal input number.

Syntax

The syntax of the ceil() function is:

CEIL(x)

The ceil() function requires one argument:

  • x: A positive or a negative decimal number (or an expression that evaluates to a decimal number).

Examples

Round up a positive decimal value

This example demonstrates how the ceil() function rounds up a positive decimal value:

SELECT CEIL (300.55);

This returns 301, as it is the nearest integer value greater than 300.55.

+------+
| f    |
+------+
| 301  |
+------+

Round up a negative decimal value

This example demonstrates how the ceil() function rounds up a negative decimal value:

SELECT CEIL(-89.9) AS "Ceil";

The output of this statement is -89, as -89 is the nearest integer value greater than or equal to -89.9.

+-------+
| Ceil  |
+-------+
| -89   |
+-------+

Use the ceil() function with a table

This example demonstrates how to use the ceil() function with a table to round up values in a specific column:

  1. First, create a table called CeilRecords:

    CREATE TABLE CeilRecords (numbers float);

INSERT INTO CeilRecords(numbers)
VALUES
    (-28.85),
    (-9.4),
    (0.87),
    (78.16),
    (42.16);

    This statement creates a table called “CeilRecords” with a column called “numbers” and insert 5 decimal values into it.

  2. Retrieve and round up the value for all records in the numbers column:

    SELECT *, CEIL(numbers) AS CeilValue FROM CeilRecords;

    The final result will contain:

    • A numbers column with initial decimal values.

    • A CeilValue column with rounded-up integer values.

      +---------+------------+
| numbers  | CeilValue  |
+---------+------------+
| -28.85  | -28        |
| -9.4    | -9         |
| 0.87    | 1          |
| 78.16   | 79         |
| 42.16   | 43         |
+---------+------------+
