# Python Number exp() Method

## Description

The method exp() returns returns exponential of x: ex.

## 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: ex.

## Example

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

```#!/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
```
