代碼1:as_tuple()方法示例

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

輸出:

Decimal value a :  -1
Decimal value b :  0.142857


Decimal a with as_tuple() method :  DecimalTuple(sign=1, digits=(1, ), exponent=0)
Decimal b with as_tuple() method :  DecimalTuple(sign=0, digits=(1, 4, 2, 8, 5, 7), exponent=-6)

代碼2:as_tuple()方法的示例

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

輸出:

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


Decimal a with as_tuple() method :  DecimalTuple(sign=1, digits=(3, 1, 4), exponent=-2)
Decimal b with as_tuple() method :  DecimalTuple(sign=0, digits=(3, 2, 1), exponent=5)
