Python math.expm1() – (e^x – 1)

Python math.expm1()

math.expm1(x) function returns the value of e raised to the power of x, minus 1, where e is the base of natural logarithm.

expm1(x) = e^x – 1

Syntax

The syntax to call expm1() function is

math.expm1(x)

where

Examples

In the following example, we find the value of expm1(x) for x = 2.

import math

x = 2
result = math.expm1(x)
print('expm1(x) :', result)

Output

expm1(x) : 6.38905609893065
