# Power Pivot Principles: The A to Z of DAX Functions – EXP

10 October 2023

*In our long-established Power Pivot Principles articles, we
continue our series on the A to Z of Data Analysis eXpression (DAX) functions. This week, we look at EXP. *

* *

*The ***EXP ***function*

The **EXP **function** **is one of the Math and trig
functions which returns *e* raised to the power of a given number. The constant *e* equals 2.71828182845904,
which is the base of the natural logarithm.
It has the following syntax:

**EXP(number)**

It has one [1] argument:

**number**: this is the exponent applied to the base*e*

Here are a few remarks about this function:

- the
**EXP**function**LN**function which is the natural logarithm of the given number **EXP(1)**returns the approximate value of*e*- if you want to calculate powers of bases other than
*e*, use the exponentiation operator (^) or the**POWER**function.

A bit of history lesson about this function:

The symbol* e *stands for Euler's number, a well-known
irrational number that is one of the most significant in mathematics. *e* is also the base of John Napier’s
Natural Logarithms.

As an example:

This returns:

Pivot in the **Blog** section. In the meantime, please remember we have
training in Power Pivot which you can find out more about **here**. If you wish to catch up on past articles in
