    All diese Makro-Konstanten (außer FE_ALL_EXCEPT) auf ganzzahlige konstante Ausdrücke, die verschiedenen Potenzen von 2, die eindeutig zu identifizieren alle unterstützten Gleitkomma-Ausnahmen sind zu erweitern. Jedes Makro wird nur definiert, wenn sie unterstützt wird .
    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.

    Die Makro konstanten FE_ALL_EXCEPT, die der bitweisen ODER aller anderen FE_* ausdehnt, wird immer definiert und ist Null, wenn Gleitkomma-Ausnahmen nicht durch die Implementierung unterstützt werden .
    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.

    FE_INEXACT
    ungenauen Ergebnis: Rundung war notwendig, um das Ergebnis der früheren Gleitkommaoperation speichern
    Original:
    inexact result: rounding was necessary to store the result of the earlier floating-point operation

    Die Implementierung kann zusätzliche Makro-Konstanten in <fenv.h> definieren, um zusätzliche Floating-Point-Ausnahmen zu ermitteln. Alle solche Konstanten beginnen mit FE_ von mindestens einem Großbuchstaben gefolgt .
    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.
