Here, We will learn how to get the absolute value of a number in go. We can use Abs() function of math package to get absolute value for the number.
Function proto type:
func Abs(no float64) float64
Return value:
Abs() function of math package returns
the absolute value of given number.
Example with code:
package main
import (
"fmt"
"math"
)
func main() {
no := math.Abs(-10)
fmt.Printf("%.2f\n", no)
no = math.Abs(10)
fmt.Printf("%.2f\n", no)
no = math.Abs(-10.0)
fmt.Printf("%.2f\n", no)
}
Output:
10.00
10.00
10.00
