`#define HUGE_VALF /implementation defined/`		(dal C++11)

`#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.
