Euler’s number, also known as Napier’s constant, is an important mathematical constant that appears in many different contexts in mathematics and physics. In R programming, the constant is represented by the letter “e”. Its value is approximately equal to 2.71828. The **exp()** function calculates the Euler’s number in R. In this guide, we will explain how to compute e in R.

## exp() Function to Calculate the e in R

The **exp()** function can also be used as an abbreviation for “exponential.” It takes a value and raises it to the power of e. This function works because it has a base of e.

#### Syntax

exp(n)

#### Argument

- n = a numeric vector

### Example

#Euler’s number exp(1) #Euler’s number to the power of 2 exp(2)

#### Output

[1] 2.718282 [1] 7.389056
