INFINITY
Infinity
Macro constant that expands to an expression of type float
.
If the implementation supports infinity values, this is defined as the value that represents a positive or unsigned infinity. Otherwise, it is a positive constant that overflows at translation time.
This may be returned by a function that signals a range error by setting errno to ERANGE.
