    #define HUGE_VAL /*implementation defined*/
    #define HUGE_VALL /*implementation defined*/
    		 (dal C++11)
    Il HUGE_VALF, HUGE_VAL e HUGE_VALL macro positivi si espandono per le espressioni costanti in virgola mobile, che risultano uguali ai valori restituiti da virgola mobile funzioni e gli operatori in caso di troppo pieno.
    Original:
    The HUGE_VALF, HUGE_VAL and HUGE_VALL macros expand to positive floating point constant expressions which compare equal to the values returned by floating-point functions and operators in case of overflow.

    In implementazioni che supportano virgola mobile infiniti, queste macro sempre si espandono per gli infiniti positivi float, double e long double, rispettivamente.
    Original:
    On implementations that support floating-point infinities, these macros always expand to the positive infinities of float, double, and long double, respectively.
