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 (see math_errhandling).
| 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.
