**Python** is a high-level programming language that provides functionalities for several operations. 

The `math` module comes with mathematical methods and constraints, which make for straightforward calculations. 

One of these is **`math.copysign()`**, which takes in two parameters and returns the first parameter's magnitude with the second parameter's sign.

# 
## Syntax

---
```
math.copysign(x, y)
```

# 
#  Parameters

- **`x`**: An integer value that is to be converted. This parameter is required.

- **`y`**: An integer value whose sign will be needed for `x`. This parameter is required.

##
## Return value

This function returns a `float` value whose magnitude is that of `x` and whose sign is that of `y`.

#import library
import math
  
r1 = math.copysign(15,-6)
print("15,-6: ", r1)

r2 = math.copysign(0,-4)
print("0,-4: ", r1)

r1 = math.copysign(-4,-13)
print("-4,-13: ", r1)

r1 = math.copysign(-10,6)
print("-10,6: ", r1)

r1 = math.copysign(-6,0)
print("-6, 0: ", r1)

r1 = math.copysign(6,0)
print("6, 0: ", r1)
