Python math function | copysign()

Last Updated : 14 Feb, 2023

math.copysign() is a function exists in Standard math Library of Python. This function returns a float value consisting of magnitude from parameter x and the sign (+ve or -ve) from parameter y.

Syntax : math.copysign(x, y)

Parameters : x : Integer value to be converted y : Integer whose sign is required

Returns : float value consisting of magnitude from parameter x and the sign from parameter y.

Time Complexity: O(1)

Auxiliary Space: O(1)

Code #1:

Python3

# Python code to demonstrate copy.sign() function
import math

def func():
    a = 5
    b = -7

    
    # implementation of copysign
    c = math.copysign(a, b)
    
    return c
    
print (func())

Output :

-5.0

Code #2:

Python3

# Python code to demonstrate copy.sign() function
import math

def func():
    a = 10
    b = 10

    
    # implementation of copysign
    c = math.copysign(a, b)
    
    return c
    
print (func())

Output :
