ABS Function

Computes the absolute value of a given numeric value. The value can be a Decimal or Integer literal or a reference to a column containing numeric values.

Basic Usage

Column reference example:

`derive type:single value:ABS(MyInteger) as:'abs_MyInteger'`

Output: Generates the new `abs_MyInteger` column containing the absolute value of each value found in the `MyInteger` column.

Numeric literal example:

`delete row:(ABS(MyInteger) == 5)`

Output: Deletes all rows from the dataset in which the absolute value of the entry in the `MyInteger` column is 5.

Syntax

`derive type:single value:ABS(numeric_value)`

ArgumentRequired?Data TypeDescription
numeric_valueYstring, decimal, or integerName of column or Decimal or Integer literal to apply to the function

numeric_value

Name of the column or numeric literal whose absolute value is to be computed.

• Missing input values generate missing results.
• Literal numeric values should not be quoted. Quoted values are treated as strings.
• Multiple columns and wildcards are not supported.

Usage Notes:

Examples

Example - Basic ABS function

Source:

Your source data looks like the following, which measures coordinate distances from a fixed point on a grid:

XY
-24
-6.2-2
0-4.2
44
15-0.05

Transform:

You can use the following transform to derive the absolute values of these columns, which now measure distance from the fixed point:

`derive type:single value: ABS(X) as: 'distanceX'`

`derive type:single value: ABS(Y) as: 'distanceY'`

Results:

XYdistanceXdistanceY
-2424
-6.2-26.22
0-4.204.2
4444
15-0.05150.05

You can then use `POW `and `SQRT` functions to compute the total distance.
