SQL abs Function | Absolute Value of an Integer

SQL abs is an inbuilt Math function in SQL Server. It returns the absolute (positive) value of a number. It is identical to modulus in mathematics. In this article, we will discuss the abs Function in SQL Server. Also, we will discuss examples of using it.

Syntax

ABS (number)

Parameters

The function expects only one parameter. The number for which you want to find the absolute value is the input to the function.

Return Value

The function returns the absolute value of the number input to it.

Input: ABS(10)
Output: 10

Input: ABS(3.5)
Output: 3.5

Input: ABS(-10)
Output: 10

Input: ABS(-3.5)
Output: 3.5

Input: ABS(0)
Output: 0

Examples

For instance, consider the following examples of using the function in SQL Queries.

mysql> SELECT ABS(10);
+---------+
| ABS(10) |
+---------+
|      10 |
+---------+

mysql> SELECT ABS(-10);
+----------+
| ABS(-10) |
+----------+
|       10 |
+----------+

mysql> SELECT ABS(3.5);
+----------+
| ABS(3.5) |
+----------+
|      3.5 |
+----------+

mysql> SELECT ABS(-3.5);
+-----------+
| ABS(-3.5) |
+-----------+
|       3.5 |
+-----------+

Conclusion

In conclusion, we discussed the ABS function in SQL Server. It can be used to ensure that the number in a variable is always positive. You can more about it on the Official Microsoft Documentation. Additionally, you can also learn about more SQL Math Functions on Concatly.
