In Tableau, the `SQRT`

function is a number function that returns the square root of a given number. It calculates the non-negative square root of a numeric value.

The syntax for the `SQRT`

function in Tableau is as follows:

```
SQRT(number)
```

`number`

represents the numeric value for which you want to calculate the square root.

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

function in Tableau:

Suppose you have a dataset with a column called "Value" that contains different numeric values.

Value |
---|

16 |

9 |

25 |

36 |

To calculate the square root of each value in the "Value" column using the `SQRT`

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:

```
SQRT([Value])
```

- Click "OK" to create the calculated field.

The calculated field, which utilizes the `SQRT`

function, will calculate the square root of each value in the "Value" column.

The resulting dataset will be as follows:

Value | Square Root |
---|---|

16 | 4.000 |

9 | 3.000 |

25 | 5.000 |

36 | 6.000 |

In this example, the `SQRT`

function calculates the square root of each value in the "Value" column. For instance, the square root of 16 is 4, the square root of 9 is 3, the square root of 25 is 5, and the square root of 36 is 6.

The `SQRT`

function is commonly used to determine the length or magnitude of a vector, calculate distances between points, or analyze data with exponential relationships. By utilizing the `SQRT`

function in Tableau, you can easily incorporate square root calculations into your visualizations and perform various mathematical operations on your data.
