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.
| Constant | Explanation |
| HUGE_VALF | Expands to positive float expression that indicates overflow |
| HUGE_VAL | Expands to positive double expression that indicates overflow, not necessarily representable as a float |
| HUGE_VALL | Expands to positive long double expression that indicates overflow, not necessarily representable as a float or double |
On implementations that support floating-point infinities, these macros always expand to the positive infinities of float, double, and long double, respectively.
