Calculate the length of the hypotenuse of a right-angle triangle
Hypotenuse is equivalent to sqrt(x*x + y*y).
Syntax
hypot ( float $x , float $y ) : float
Parameters
x
Length of first side
y
Length of second side
Return
Calculated length of the hypotenuse
Examples
1
<? $x = 3; $y = 4; $return = hypot($x, $y); echo $return; ?>
5
2
<? $x = 3; $y = 4; $return = sqrt(($x * $x) + ($y * $y)); echo $return; ?>
5
