Defined in header <cmath>
#define INFINITY /*implementation defined*/
(since C++11)

The macro INFINITY expands to constant expression of type float which evaluates to positive or unsigned infinity, if supported by implementation, or to a positive value that is guaranteed to overflow a float at compile time.
