Question

How to calculate the Euclidean distance between two points in Go

Answer 1

// The Euclidean distance is a measure of the straight-line distance 
// between two points in a 2D or 3D space

package main

import (
    "fmt"
    "math"
)

// CalculateEuclideanDistance computes the Euclidean distance between two 2D points
func CalculateEuclideanDistance(x1, y1, x2, y2 float64) float64 {
    return math.Sqrt(math.Pow(x2-x1, 2) + math.Pow(y2-y1, 2))
}

func main() {
    x1, y1 := 3.0, 4.0
    x2, y2 := 5.0, 9.0

    distance := CalculateEuclideanDistance(x1, y1, x2, y2)
    fmt.Printf("Euclidean Distance: %.5f\n", distance)
}
