long double hypotl( long double x, long double y );
(desde C99)
Calcula la raíz cuadrada de la suma de los cuadrados de x y y, sin desbordamiento o subdesbordamiento indebida en fases intermedias de la computación. Esta es la longitud de la hipotenusa de un triángulo rectángulo con lados de longitud x y y, o la distancia de la (x,y) punto desde el origen (0,0), o la magnitud de un número complejo x+iy
Original:
Computes the square root of the sum of the squares of x and y, without undue overflow or underflow at intermediate stages of the computation. This is the length of the hypotenuse of a right-angled triangle with sides of length x and y, or the distance of the point (x,y) from the origin (0,0), or the magnitude of a complex number x+iy
