[modifica] Note

Funzione non qualificato (sqrt) viene utilizzato per eseguire il calcolo. Se tale funzione non è disponibile, std::sqrt viene utilizzato a causa di ricerca tesi a carico.
Original:
Unqualified function (sqrt) is used to perform the computation. If such function is not available, std::sqrt is used due to argument dependent lookup.
