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
