Java Math hypot() method with Example
  • Last Updated : 06 Apr, 2018

java.lang.Math.hypot() function is an inbuilt math function in Java that returns the Euclidean norm,  \sqrt{(x * x + y * y)} . The function returns sqrt(x2 + y2) without intermediate overflow or underflow.

  • If either argument is infinite, then the result is positive infinity.
  • If either argument is NaN and neither argument is infinite, then the result is NaN.

Syntax :

public static double hypot(double x, double y)
Parameter :
x and y are the values. 

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

Example 1 : To show working of java.lang.Math.hyptot() method.

        double negativeInfinity = 
               Double.NEGATIVE_INFINITY;
        double nan = Double.NaN;
  
        // when 1 or more argument is NAN
        result = Math.hypot(nan, y);
        System.out.println(result);
  
        // when both arguments are infinity
        result = Math.hypot(positiveInfinity, 
                            negativeInfinity);
        System.out.println(result);
    }
