Python|十进制 as_tuple() 方法

Decimal#as_tuple() : as_tuple()是一个 Decimal 类方法，它返回 Decimal 值的命名元组表示。

Syntax: Decimal.as_tuple()

Parameter: Decimal values

Return: tuple with values
– sign
– digits
– exponent

代码 #1：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(-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())

输出 ：

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)

代码 #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())

输出 ：

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)
