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