INFINITY

From cppreference.com
< cpp‎ | numeric‎ | math
 
C++
 
Numerics library
 
Common mathematical functions
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.
