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

 In Tableau, the SQUARE function is a number function that returns the square of a given number. It calculates the square value of a numeric input.

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

SQUARE(number)

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

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

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

Value
2
4
6
8

To calculate the square of each value in the "Value" column using the SQUARE 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:

SQUARE([Value])

4. Click "OK" to create the calculated field.

The calculated field, which utilizes the SQUARE function, will calculate the square of each value in the "Value" column.

The resulting dataset will be as follows:

Value	Square
2	4
4	16
6	36
8	64

In this example, the SQUARE function calculates the square of each value in the "Value" column. For instance, the square of 2 is 4, the square of 4 is 16, the square of 6 is 36, and the square of 8 is 64.

The SQUARE function is commonly used to analyze data with quadratic relationships, calculate areas or volumes, or perform various mathematical operations. By utilizing the SQUARE function in Tableau, you can easily incorporate square calculations into your visualizations and manipulate your data accordingly.
