Il valore del std::numeric_limits<T>::radix è la base del sistema numerico utilizzato nella rappresentazione del tipo. È 2 per tutti i tipi numerici binari, ma può essere, per esempio, 10 per IEEE 754 decimali tipi a virgola mobile o per terzi interi codice binario decimale. Questa costante è significativo per tutte le specializzazioni.

Original:

It is 2 for all binary numeric types, but it may be, for example, 10 for IEEE 754 decimali tipi a virgola mobile or for third-party codice binario decimale integers. This constant is meaningful for all specializations.
