Explain the Number Function ' POWER ' in Tableau with Example?

 In Tableau, the POWER function is a number function that calculates the power of a given base raised to a specified exponent. It returns the result of raising the base to the exponent.

The syntax for the POWER function in Tableau is as follows:

POWER(base, exponent)
  • base represents the base number.
  • exponent represents the power to which the base number is raised.

Here's an example to illustrate the usage of the POWER function in Tableau:

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


To calculate the square of each value in the "Value" column using the POWER function, you can create a calculated field in Tableau:

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

POWER([Value], 2)
  1. Click "OK" to create the calculated field.

The calculated field, which utilizes the POWER function, will raise each value in the "Value" column to the power of 2.

The resulting dataset will be as follows:


In this example, the POWER function calculates the square of each value in the "Value" column by raising it to the power of 2.

The POWER function can be used to perform various mathematical calculations, such as calculating exponents, roots, or any other power-based operations. By utilizing the POWER function in Tableau, you can easily incorporate these calculations into your visualizations and gain insights from your data.
