Calculate exponential of a number in R Programming – exp() Function

** exp()** function in R Language is used to calculate the power of e i.e. e^y or we can say exponential of y. The value of e is approximately equal to 2.71828…..

Syntax:exp(y)

Parameters:y:It is any valid R number either positive or negative.

Returns:Floating point number by calculating e^y.

**Example 1:**

`# R program to calculate exp value ` ` ` `# Using exp() method ` `answer1 <` `-` `exp(` `4` `) ` `answer2 <` `-` `exp(` `-` `3` `) ` `answer3 <` `-` `exp(` `0.0` `)` ` ` `print` `(answer1) ` `print` `(answer2) ` `print` `(answer3) ` |

**Output:**

54.59815 0.04978707 1

**Example 2:**

`# R program to calculate exp value ` ` ` `# Using exp() method ` `answer1 <` `-` `exp(c(pi, exp(` `1` `))) ` ` ` `print` `(answer1) ` |

**Output:**

23.14069 15.15426
