Gleitkomma-Spezifikation in Simulink
Da Single-Precision-Zahlen nur 32 Bit verwenden, benötigen sie weniger Speicherplatz als Double-Precision-Zahlen, bieten aber dennoch viele der Vorteile der Gleitkomma-Arithmetik. Der Datentyp "Half-Precision" erfordert nur 16 Bit Speicherplatz; durch die Gleitkomma-Darstellung kann er jedoch breitere dynamische Bereiche als Integer- oder Festkomma-Datentypen derselben Größe verarbeiten.
