Decimal#copy_sign() : copy_sign() is a Decimal class method which returns the copy of the first Decimal value with the sign set to be the same as the sign of the second Decimal value.
Syntax: Decimal.copy_sign() Parameter: Decimal values Return: the copy of the first Decimal value with the sign set to be the same as the sign of the second Decimal value.
Code #1 : Example for copy_sign() method
# Python Program explaining # copy_sign() 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_sign() method print ("\n\nDecimal a with copy_sign() method : ", a.copy_sign(a))   print ("Decimal a with copy_sign() method : ", a.copy_sign(b))   print ("Decimal b with copy_sign() method : ", b.copy_sign(a)) |
Output :
Decimal value a : -1 Decimal value b : 0.142857 Decimal a with copy_sign() method : -1 Decimal a with copy_sign() method : 1 Decimal b with copy_sign() method : -0.142857
Code #2 : Example for copy_sign() method
# Python Program explaining # copy_sign() 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_sign() method print ("\n\nDecimal a with copy_sign() method : ", a.copy_sign(a))   print ("Decimal a with copy_sign() method : ", a.copy_sign(b))   print ("Decimal b with copy_sign() method : ", b.copy_sign(a)) |
Output :
Decimal value a : -3.14 Decimal value b : 3.21E+7 Decimal a with copy_sign() method : -3.14 Decimal a with copy_sign() method : 3.14 Decimal b with copy_sign() method : -3.21E+7
