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

 In Tableau, the EXP function is a number function that calculates the exponential value of a given number. It returns the result of raising the mathematical constant e (approximately 2.71828) to the power of the specified number.

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

EXP(number)

• number is the numeric value for which you want to calculate the exponential value.

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

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

Power
2.0
3.5
1.8
0.0

To calculate the exponential value for the "Power" column using the EXP 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:

EXP([Power])

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

The calculated field, which utilizes the EXP function, will calculate the exponential value for each value in the "Power" column.

The resulting dataset will be as follows:

Power	Exponential Value
2.0	7.3891
3.5	33.1155
1.8	6.0496
0.0	1.0000

In this example, the EXP function calculates the exponential value for each number in the "Power" column. For instance, the exponential value of 2.0 is approximately 7.3891, the exponential value of 3.5 is approximately 33.1155, and so on.

The EXP function is particularly useful when working with exponential growth or decay scenarios, such as calculating compound interest, population growth, or decay rates. By utilizing the EXP function in Tableau, you can perform these calculations and analyze data involving exponential values.
