The Hypot() function returns the square root of the sum of two squares. In other words, the method returns the result of the following formula:

hypotenuse=(xx)+(yy)hypotenuse = \sqrt{(x * x) + (y * y)}

Syntax

import math

result := math.Hypot(x, y)

Hypot() accepts two arguments (x , y) of type float64 and returns a value of type float64.

Note:

  • If either argument is negative, or both, the result is positive.
  • If either argument is positive infinity (+Inf), the result will be positive infinity.
  • If 0 is passed as both arguments, the result is 0. If one of the arguments is 0 the result is equal to the other argument.
  • If either argument passed is NaN, the result will be NaN.

Example

package main
import("fmt"
"math")
func main() {
fmt.Printf("Hypotenuse of 3 and 4 = %f\n", math.Hypot(3 , 4))
fmt.Printf("Hypotenuse of -1.5 and -1.5 = %f\n", math.Hypot(-1.5,-1.5))
}

The above example results in the following output:

Hypotenuse of 3 and 4 = 5.000000
Hypotenuse of -1.5 and -1.5 = 2.121320

Codebyte Example

The runnable example of the Hypot() function of the cases where 0 or a negative number is at least one of the arguments.
