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

Compute the Exponential minus 1 of a Number in R Programming - expm1() Function

Last Updated : 10 Jun, 2020

expm1() function in R Language is used to compute exponential minus 1 i.e, exp()-1.

Syntax: expm1(x) Parameters: a, b: number or number vector

Example 1:

Python3

# R program to illustrate
# expm1 function

# Calling the expm1() function
expm1(4)  # e5 -1 
expm1(10)
expm1(15)

Output:

[1] 53.59815
[1] 22025.47
[1] 3269016

Example 2:

Python3

# R program to illustrate
# expm1 function

# Calling the expm1() function
expm1(rep(1:5))
expm1(rep(5:8))

Output:

[1]  1.718282   6.389056  19.085537  53.598150 147.413159
[1]  147.4132  402.4288 1095.6332 2979.9580
