The following method returns the hypotenuse of the right triangle whose two legs are passed as parameters:

  // Hypotenuse method
  // Hypotenuse ( real ; real ) -> real
  // Hypotenuse ( legA ; legB ) -> Hypotenuse
 var $0;$1;$2 : Real
 $0:=Square root(($1^2)+($2^2))

For instance, Hypotenuse (4;3) returns 5.
