Syntax: Decimal.is_nan()
Parameter: Decimal values
Return: true – if the Decimal value is NaN value; otherwise false
Code #1 : Example for is_nan() method
# Python Program explaining # is_nan() 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_nan() method print ("\n\nDecimal a with is_nan() method : ", a.is_nan()) print ("Decimal b with is_nan() method : ", b.is_nan()) |
Output :
Decimal value a : -1 Decimal value b : NaN Decimal a with is_nan() method : False Decimal b with is_nan() method : True
Code #2 : Example for is_nan() method
# Python Program explaining # is_nan() 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_nan() method print ("\n\nDecimal a with is_nan() method : ", a.is_nan()) print ("Decimal b with is_nan() method : ", b.is_nan()) |
Output :
Decimal value a : -3.14 Decimal value b : 3.21E+7 Decimal a with is_nan() method : False Decimal b with is_nan() method : False
