Here, We will learn how to get value with the magnitude of x and the sign of y in go. We can get it by using Copysign() function in math package in go golang.
Function prototype:
func Copysign(x, y float64) float64
Return value:
Copysign() function in math package returns
a value with the magnitude of x and the sign of y.
Example with code:
package main
import (
"fmt"
"math"
)
func main() {
no := math.Copysign(2.2, -1)
fmt.Printf("%.2f\n", no)
no = math.Copysign(1.2, -2)
fmt.Printf("%.2f\n", no)
no = math.Copysign(0.2, 1)
fmt.Printf("%.2f\n", no)
no = math.Copysign(-2.2, -1)
fmt.Printf("%.2f\n", no)
no = math.Copysign(-5, 1)
fmt.Printf("%.2f\n", no)
}
Output:
-2.20
-1.20
0.20
-2.20
5.00
