Python | Decimal exp() method

Last Updated : 05 Sep, 2019

Decimal#exp() : exp() is a Decimal class method which returns the value of the (natural) exponential function e**x at the given number

Syntax: Decimal.exp() Parameter: Decimal values Return: the value of the (natural) exponential function e**x at the given number

Code #1 : Example for exp() method

Python3

# Python Program explaining 
# exp() method

# loading decimal library
from decimal import *


# Initializing a decimal value
a = Decimal(-1)

b = Decimal('0.142857')

# printing Decimal values
print ("Decimal value a : ", a)
print ("Decimal value b : ", b)


# Using Decimal.exp() method
print ("\n\nDecimal a with exp() method : ", a.exp())

print ("Decimal b with exp() method : ", b.exp())

Output :

Decimal value a :  -1
Decimal value b :  0.142857


Decimal a with exp() method :  0.3678794411714423215955237702
Decimal b with exp() method :  1.153564830100120253802476512

Code #2 : Example for exp() method

Python3

# Python Program explaining 
# exp() method

# loading decimal library
from decimal import *


# Initializing a decimal value
a = Decimal('-3.14')

b = Decimal('7.555')

# printing Decimal values
print ("Decimal value a : ", a)
print ("Decimal value b : ", b)


# Using Decimal.exp() method
print ("\n\nDecimal a with exp() method : ", a.exp())

print ("Decimal b with exp() method : ", b.exp())

Output :

Decimal value a :  -3.14
Decimal value b :  7.555


Decimal a with exp() method :  0.04328279790196590079772976615
Decimal b with exp() method :  1910.270243928773816178935745
