How to use Math.hypot() in Java?

The hypot() method is a static method of the java.lang.Math library. It takes two numbers and returns the square root of x2x^{2} + y2y^{2} without any intermediate underflow or overflow.

There are special cases regarding this function:

  • The result will be positiveinfinity if any of the parameters are infinite.

  • The result will be NaN if any of the parameters are NaN and none of them are infinite.

Syntax


public static double hypot(double x, double y)

Parameters

This method will take two numbers of primitive data type double:

  • x contains the first argument.
  • y contains the second argument.

Return value

This function will return the answer of √(x2x^{2} + y2y^{2}) without any overflow or underflow of double type.

Example

This code illustrates how to use the hypot() method to compute sqrt (x2x^{2} + y2y^{2}).

  • We initialized num1= 32176.2 and num2= -298.77, then called the function to perform the calculations.
  • It returns 32177.5870.
import java.lang.*;
public class EdPresso {
public static void main(String[] args) {
//initializng the variables
double num1 = 32176.2;
double num2 = -298.77;
//calling the hypot method
//and printing the output
System.out.println("answer= " + Math.hypot(num1, num2));
}
}
