代码 #1：number_class() 方法的示例

# Python Program explaining 
# number_class() method
  
# loading decimal library
from decimal import *
  
  
# 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())

输出 ：

Decimal value a :  -1
Decimal value b :  0.142857


Decimal a with number_class() method :  -Normal
Decimal b with number_class() method :  +Normal

代码 #2：number_class() 方法的示例

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

输出 ：

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


Decimal a with number_class() method :  -Normal
Decimal b with number_class() method :  +Normal
