INFINITY
From cppreference.com
Defined in header
<cmath>

#define INFINITY /*implementation defined*/

(since C++11) | |
If the implementation supports floating-point infinities, the macro INFINITY
expands to constant expression of type float which evaluates to positive or unsigned infinity.
If the implementation does not support floating-point infinities, the macro INFINITY
expands to a positive value that is guaranteed to overflow a float at compile time, and the use of this macro generates a compiler warning.
