Negative numbers line up on the left; positive numbers run along the track to the right. So, the number –4.0 is 4 units away from zero. The number –45.3 is 45.3 units away from zero and the number 10 is 10 units away from zero. Therefore, the absolute value of any number is really a positive number (or zero).

The absolute value of 65 is 65 because absolute value is the number of units away a number is from zero.

The absolute value of the number is represented by neglecting the negative sign. Hence, for negative numbers, the absolute value is the magnitude of the number without the sign. Hence, the absolute value of -36 is 36.

On a number line it is the distance between the number and zero. The symbol for absolute value is to enclose the number between vertical bars such as |-20| = 20 and read “The absolute value of -20 equals 20”.

Excel ABS Function

1. Summary.
2. Find the absolute value of a number.
3. A positive number.
4. =ABS (number)
5. number – The number to get the absolute value of.
6. Version.
7. For example, ABS(-3) returns a value of 3 and ABS(3) returns a value of 3, because the ABS function returns a number’s distance from zero.

The ABS function in Excel returns the absolute value of a number. In other words: the ABS function removes the minus sign (-) from a negative number, making it positive. 1.

ABS() function : This function in SQL Server is used to return the absolute value of a specified number. Absolute value is used for depicting the distance of a number on the number line from 0. The direction of the number from zero is not considered since the absolute value of a number is never negative.

SQL ABS() function is used to get the absolute value of a number passed as an argument. An expression which is a numeric value or numeric data type. The bit data type is not allowed. All of above platforms support the SQL syntax of ABS().

In SQL Server, the T-SQL SIGN() function returns the sign of a number. In other words, it indicates whether or not the value is a positive number, a negative number, or zero. You provide the number as an argument when calling the function.

PostgreSQL ABS Function

1. ABS(numeric_expression) Arguments.
2. SELECT ABS( 100 – 250 ); Here is the result:
3. 150. Besides the ABS() function, you can use the absolute operator @, for example:
4. SELECT @ -15. It returned 15 as expected.
5. -15.

Compares two expressions (a comparison operator). When you compare nonnull expressions, the result is TRUE if the left operand is not equal to the right operand; otherwise, the result is FALSE. If either or both operands are NULL, see the topic SET ANSI_NULLS (Transact-SQL).

Multiply by -1 as in -1*a. value to change a. value from positive to negative. Would return a column with header “neg_val” and entries below it resulting from the multiplication of the table value by negative 1.

SQL Server SIGN() Function The SIGN() function returns the sign of a number. This function will return one of the following: If number > 0, it returns 1. If number = 0, it returns 0.
