Python|小数 shift() 方法

Decimal#shift() : shift()是一个 Decimal 类方法，它返回 x, y 次的移位副本

Syntax: Decimal.shift()

Parameter: Decimal values

Return: the shifted copy of x, y times

代码 #1：shift() 方法的示例

# Python Program explaining 
# shift() method
  
# loading decimal library
from decimal import *
  
  
# Initializing a decimal value
a = Decimal(1)
  
b = Decimal(2)
  
# printing Decimal values
print ("Decimal value a : ", a)
print ("Decimal value b : ", b)
  
  
# Using Decimal.shift() method
print ("\n\nDecimal a with shift() method : ", a.shift(b))
  
print ("Decimal b with shift() method : ", b.shift(b))

输出 ：

Decimal value a :  1
Decimal value b :  2


Decimal a with shift() method :  100
Decimal b with shift() method :  200

代码 #2：shift() 方法的示例

# Python Program explaining 
# shift() method
  
# loading decimal library
from decimal import *
  
  
# Initializing a decimal value
a = Decimal(300)
  
b = Decimal(15)
  
  
# printing Decimal values
print ("Decimal value a : ", a)
print ("Decimal value b : ", b)
  
  
# Using Decimal.shift() method
print ("\n\nDecimal a with shift() method : ", a.shift(b))
  
print ("Decimal b with shift() method : ", b.shift(b))

输出 ：

Decimal value a :  300
Decimal value b :  15


Decimal a with shift() method :  300000000000000000
Decimal b with shift() method :  15000000000000000
