hypot

(PHP 4 >= 4.1.0, PHP 5, PHP 7)

Calculate the length of the hypotenuse of a right-angle triangle

float hypot ( float $x, float $y )

hypot() returns the length of the hypotenuse of a right-angle triangle with sides of length x and y, or the distance of the point (x, y) from the origin. This is equivalent to sqrt(x*x + y*y).

Parameters:

Length of first side

Length of second side

Returns:

Calculated length of the hypotenuse
