Question

How to calculate the Euclidean distance between two points in Kotlin

Answer 1

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

// calculateEuclideanDistance computes the Euclidean distance between two 2D points
fun calculateEuclideanDistance(x1: Double, y1: Double, x2: Double, y2: Double): Double {
    return Math.sqrt(Math.pow(x2 - x1, 2.0) + Math.pow(y2 - y1, 2.0))
}

fun main() {
    val x1 = 3.0
    val y1 = 4.0
    val x2 = 5.0
    val y2 = 9.0

    val distance = calculateEuclideanDistance(x1, y1, x2, y2)
    println("Euclidean Distance: %.5f".format(distance))
}
