El valor de std::numeric_limits<T>::has_infinity es true para todo tipo T capaces de representar el infinito positivo como un valor especial distinto. Esta constante es significativa para todos los tipos de punto flotante y se garantiza que sea true si std::numeric_limits<T>::is_iec559==true .
Original:
