Question

How to compute the hypotenuse h of the triangle in Scala

Answer 1

object HypotenuseCalculator {
  def main(args: Array[String]): Unit = {
    val a: Double = 7
    val b: Double = 5

    // Method 1: Using Math.sqrt and Math.pow
    val h1 = Math.sqrt(Math.pow(a, 2) + Math.pow(b, 2))
    println(f"The hypotenuse (h) is: $h1%.6f")

    // Method 2: Using direct multiplication
    val h2 = Math.sqrt(a * a + b * b)
    println(f"The hypotenuse (h) is: $h2%.6f")

    // Method 3: Using Math.hypot (available in Java 1.5+ / Scala via Java interop)
    val h3 = Math.hypot(a, b)
    println(f"The hypotenuse (h) is: $h3%.6f")
  }
}


 
/*
run:

The hypotenuse (h) is: 8.602325
The hypotenuse (h) is: 8.602325
The hypotenuse (h) is: 8.602325
