Description

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

Syntax

Following is the syntax for exp() method −

import math

math.exp( x )

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

Live Demo

#!/usr/bin/python
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(119L) : ", math.exp(119L)
print "math.exp(math.pi) : ", math.exp(math.pi)

When we run above program, it produces following result −

math.exp(-45.17) :  2.41500621326e-20
math.exp(100.12) :  3.03084361407e+43
math.exp(100.72) :  5.52255713025e+43
math.exp(119L) :  4.7978133273e+51
math.exp(math.pi) :  23.1406926328
