Code #1 : Example for is_qnan() method

# Python Program explaining
# is_qnan() method

# loading decimal library
from decimal import *


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

b = Decimal('nan')

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


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

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

Output :

Decimal value a :  -1
Decimal value b :  NaN


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

Code #2 : Example for is_qnan() method

# Python Program explaining
# is_qnan() method

# loading decimal library
from decimal import *


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

b = Decimal('321e+5')

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


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

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

Output :

Decimal value a :  -3.14
Decimal value b :  3.21E+7


Decimal a with is_qnan() method :  False
Decimal b with is_qnan() method :  False
