Python 3 - Number exp() Method

Description

The exp() method returns exponential of x: e^x.

Syntax

Following is the syntax for the exp() method −

import math

math.exp( x )

Note − This function is not accessible directly. Therefore, we need to import the math module and then we need to call this function using the math static object.

Parameters

x − This is a numeric expression.

Return Value

This method returns exponential of x: e^x.

Example

The following example shows the usage of exp() method.

#!/usr/bin/python3
import math   # This will import math module

print ("math.exp(-45.17) : ", math.exp(-45.17))
print ("math.exp(100.12) : ", math.exp(100.12))
print ("math.exp(100.72) : ", math.exp(100.72))
print ("math.exp(math.pi) : ", math.exp(math.pi))

Output

When we run the above program, it produces the following result −

math.exp(-45.17) :  2.4150062132629406e-20
math.exp(100.12) :  3.0308436140742566e+43
math.exp(100.72) :  5.522557130248187e+43
math.exp(math.pi) :  23.140692632779267
