18 Digit Packed BCD

18 Digit Packed BCD
18 Digit Packed BCD
 
[dt. »komprimierte 18-stellige binärkodierte Dezimalzahlen«], ein Datentyp beim 80386-Prozessor sowie seinen Nachfolgern. Er umfasst eine Länge von 80 bit: Die ersten 72 bit werden für die Darstellung von 18 nach BCD kodierten Dezimalstellen verwendet (jede Stelle benötigt 4 bit), darauf folgen sieben freie Bits und mit dem letzten Bit wird das Vorzeichen dargestellt.
