O valor de std::numeric_limits<T>::digits é o número de dígitos de base radix-que podem ser representados pela
T tipo sem alterações. Para tipos inteiros, este é o número de bits não contando o bit de sinal. Por tipos de ponto flutuante, este é o número de dígitos na 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.The text has been machine-translated via Google Translate.
