The hypot() function is a built-in mathematical function in PHP and returns the square root of sum of square of arguments passed. It finds the hypotenuse, hypotenuse is the longest side of a right angled triangle. It is calculated by the formula :
where x and y are the other two sides of the triangle.
- x : the length of first side.
- y: the length of the second side.
Return Type: The return type of hypot(x,y) is Float and it returns the square root of squares of values passed to it as parameters.
Input : x=3, y=4 Output :5 Input :x=9, y=10 Output : 13.453624047074
