Note

Funzione non qualificato (pow) viene utilizzato per eseguire il calcolo. Se tale funzione non è disponibile, std::pow viene utilizzato a causa di ricerca tesi a carico.

Original:

Unqualified function (pow) is used to perform the computation. If such function is not available, std::pow is used due to argument dependent lookup.
