What is the use of Math.hypot() function in JavaScript?
Math.hypot()
Math.Hypot() method is used to find the square root of the sum of the squares of the elements that are passed to it as arguments. This method is actually used to find the hypotenuse of a right-angle triangle whose sides are passed as arguments into it.
syntax
Math.hypot(arg1, arg2,....);
Example
In the following example, sides of a right-angle triangle are passed to find the hypotenuse. If any value is can't be converted to a number then NaN will be displayed as output.
<html> <body> <script> document.write(Math.hypot(7, 24)); document.write("</br>"); document.write(Math.hypot(7, "hi")); </script> </body> </html> Output
25 NaN
This method even accepts negative values as arguments and tries to give the square root of some of their squares as output.
Example
<html> <body> <script> document.write(Math.hypot(-7, -24)); document.write("</br>") document.write(Math.hypot(-3, -4)) </script> </body> </html> Output
25 5
This method can take multiple values, more than two, and tries to give the square root of some of their squares.
Example
<html> <body> <script> document.write(Math.hypot(1, 2, 3)); </script> </body> </html>
Output
