Returns sqrt(x² +y²) without intermediate overflow or underflow.

Usage

From source file:Main.java

public static void main(String[] args) {
    double d1 = 3, d2 = 4, d3 = 6;

    System.out.println("hypotenuse value of  d1 and d2 = " + StrictMath.hypot(d1, d2));

    System.out.println("hypotenuse value of d2 and d3 = " + StrictMath.hypot(d2, d3));
