In Tableau, the `ABS`

function is a number function that returns the absolute value of a given number. The absolute value represents the magnitude of a number without considering its sign (+ or -). The `ABS`

function ensures that the result is always a positive value or zero.

The syntax for the `ABS`

function in Tableau is as follows:

```
ABS(number)
```

`number`

is the numeric value for which you want to calculate the absolute value.

Here's an example to illustrate the usage of the `ABS`

function in Tableau:

Let's consider a dataset with a column called "Sales" that contains different sales values, including positive and negative numbers.

Sales |
---|

100 |

-50 |

200 |

-150 |

To calculate the absolute values of the "Sales" column using the `ABS`

function, you can create a calculated field in Tableau:

- Right-click on a blank area in the "Data" pane in Tableau.
- Select "Create Calculated Field."
- In the formula editor, enter the following expression:

```
ABS([Sales])
```

- Click "OK" to create the calculated field.

The calculated field, which utilizes the `ABS`

function, will calculate the absolute value for each value in the "Sales" column.

The resulting dataset will be as follows:

Sales | Absolute Sales |
---|---|

100 | 100 |

-50 | 50 |

200 | 200 |

-150 | 150 |

In this example, the `ABS`

function calculates the absolute value of each sales value, disregarding the positive or negative sign. For instance, the absolute value of -50 is 50, and the absolute value of -150 is 150.

By utilizing the `ABS`

function, you can ensure that you are working with the magnitude of numbers and remove any potential negative values, allowing for consistent calculations and analysis of numerical data in Tableau.
