    static const int digits
    		 (fino al c++11)
    static constexpr int digits
    		 (dal C++11)
    Il valore del std::numeric_limits<T>::digits è il numero di cifre in base-radix che possono essere rappresentati dalla T tipo senza cambiamenti. Per i tipi interi, questo è il numero di bit senza contare il bit di segno. Per i tipi a virgola mobile, questo è il numero di cifre nella mantissa.
    Original:
    The value of std::numeric_limits<T>::digits is the number of digits in base-radix that can be represented by the type T without change. For integer types, this is the number of bits not counting the sign bit. For floating-point types, this is the number of digits in the mantissa.
