Decimal#copy_negate() : copy_negate() is a Decimal class method which returns the negation of Decimal value.

Syntax: Decimal.copy_negate()

Parameter: Decimal values

Return: the negation of Decimal value

Code #1 : Example for copy_negate() method

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

print ("Decimal b with copy_negate() method : ", b.copy_negate())

Output :

Decimal value a :  -1
Decimal value b :  0.142857


Decimal a with copy_negate() method :  1
Decimal b with copy_negate() method :  -0.142857

Code #2 : Example for copy_negate() method

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

print ("Decimal b with copy_negate() method : ", b.copy_negate())

Output :

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


Decimal a with copy_negate() method :  3.14
Decimal b with copy_negate() method :  -3.21E+7
