Todas estas constantes macro (excepto FE_ALL_EXCEPT) extender a expresiones constantes enteros que son potencias distintas de 2, que identifican de forma única todos apoyados excepciones de punto flotante. Cada macro se define sólo si es respaldada .
Original:
All these macro constants (except FE_ALL_EXCEPT) expand to integer constant expressions that are distinct powers of 2, which uniquely identify all supported floating-point exceptions. Each macro is only defined if it is supported.

El FE_ALL_EXCEPT macro constante, que se expande a la OR bit a bit de todos FE_* otra parte, siempre se define y es cero si excepciones de punto flotante no son compatibles con la puesta en práctica .
Original:
The macro constant FE_ALL_EXCEPT, which expands to the bitwise OR of all other FE_*, is always defined and is zero if floating-point exceptions are not supported by the implementation.

La aplicación puede definir constantes adicionales macro en <fenv.h> para identificar otras excepciones de punto flotante. Todas las constantes tales comenzar con FE_ seguido por al menos una letra mayúscula .
Original:
The implementation may define additional macro constants in <fenv.h> to identify additional floating-point exceptions. All such constants begin with FE_ followed by at least one uppercase letter.
