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:
It has one  argument:
- number: this is the exponent applied to the base e
Here are a few remarks about this function:
- the EXP function is the inverse of the 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.
