# 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.number_class() method
print ("\n\nDecimal a with number_class() method:", a.number_class())
print ("Decimal b with number_class() method:", b.number_class())
