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
