Python math function | copysign()

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
