Syntax: Decimal.logical_invert()

Parameter: Decimal values

Return: the digit-wise inversion of the Decimal values.

代码 #1：logical_invert() 方法的示例

# Python Program explaining 
# logical_invert() method
  
# loading decimal library
from decimal import *
  
  
# Initializing a decimal value
a = Decimal('0')
  
b = Decimal('1')
  
# printing Decimal values
print ("Decimal value a : ", a)
print ("Decimal value b : ", b)
  
  
# Using Decimal.logical_invert() method
print ("\n\nDecimal a with logical_invert() method : ", a.logical_invert())
  
print ("Decimal b with logical_invert() method : ", b.logical_invert())

输出 ：

Decimal value a :  0
Decimal value b :  1


Decimal a with logical_invert() method :  1111111111111111111111111111
Decimal b with logical_invert() method :  1111111111111111111111111110
