Math Class static double hypot(double d1, double d2)

  • This method is available in java.lang package.
  • This method is used to return the square root of (square(d1)+ square(d2)) without any intermediate operations or in other words it returns the sqrt(square(d1)+ square(d2)).
  • This is a static method so it is accessible with the class name too.
  • The return type of this method is double that means it returns the square root of the given argument.
  • In this method, we pass two parameters as arguments and both of the parameters are of double type.
  • This method does not throw any exception.

Syntax:

    public static double hypot(double d1 , double d2){
    }

Parameter(s): d1 and d2 – both are the double values which will be used to find the square root of (d1*d1 + d2*d2).

Return value:

The return type of this method is double, it returns the Euclidean norm i.e. square root of (d12+d22).

Note:

  • If we pass an infinity in any of the given arguments, it returns the infinity.
  • If we pass "NaN" in any of the given arguments, it returns the "NaN".

Java program to demonstrate example of hypot(double d1, double d2) method

// Java program to demonstrate the example of 
// hypot(double d1 , double d2) method of Math Class

public class HypotMethod {
    public static void main(String[] args) {
        // Here we are declaring few variables
        double d1 = 7.0 / 0.0;
        double d2 = 5.0;
        double d3 = 10.0;

        // displaying the values
        System.out.println("d1: " + d1);
        System.out.println("d2: " + d2);
        System.out.println("d3: " + d3);

        // Here , we will get (NaN) because we are passing 
        // parameter whose value is (d2,d1)
        System.out.println("Math.hypot(d2,d1): " + Math.hypot(d2, d1));

        // Here , we will get (sqrt(sq(d2)+sq(d3))) because 
        // we are passing parameter whose value is (d2,d3)
        System.out.println("Math.hypot(d2,d3): " + Math.hypot(d2, d3));
    }
}

Output

E:\Programs>javac HypotMethod.java

E:\Programs>java HypotMethod
d1: Infinity
d2: 5.0
d3: 10.0
Math.hypot(d2,d1): Infinity
Math.hypot(d2,d3): 11.180339887498949
