Python | Decimal is_zero() method

Last Updated : 05 Sep, 2019

Decimal#is_zero() : is_zero() is a Decimal class method which checks whether the Decimal value is zero value.

Syntax: 
Decimal.is_zero()

Parameter: 
Decimal values

Return: 
true - if the Decimal value is zero value; otherwise false

Code #1 : Example for is_zero() method

Python3

# Python Program explaining 
# is_zero() method

# loading decimal library
from decimal import *


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

b = Decimal(0)

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


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

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

Output :

Decimal value a :  -1
Decimal value b :  0


Decimal a with is_zero() method :  False
Decimal b with is_zero() method :  True

Code #2 : Example for is_zero() method

Python3

# Python Program explaining 
# is_zero() method

# loading decimal library
from decimal import *


# Initializing a decimal value
a = Decimal(-0)

b = Decimal('321e + 5')

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


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

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

Output :

Decimal value a :  0
Decimal value b :  3.21E+7


Decimal a with is_zero() method :  True
Decimal b with is_zero() method :  False
