The initial design called for two octuple mountings for the QF 2-pounder Mk. The two funnels were trunked into one and a single octuple 2-pounder mountings was added. This 256-bit octuple precision is for applications requiring results in higher than quadruple precision. Short-range air defence was provided by 48 QF 2-pounder "pom-pom" guns in six octuple mountings. The octuple 2-pounder guns that had originally been designed in were also finally added. VIII "pom-pom" anti-aircraft guns in six octuple, power-driven, mountings. However octuple sculls are not used in main competitions. There is no known hardware implementation of octuple precision. The Royal Navy used similar weapons in quad or even octuple mounts. The Mark VI octuple mount weighed 16 tons. "Glorious" received three octuple Mark VI mounts in the same locations. It was certified octuple platinum by the Recording Industry Association of America. Octuple precision is rarely implemented since usage of it is extremely rare. The single was certified octuple platinum by the Recording Industry Association of America. In modern theoretical contexts, it is occasionally called an octuple whole note .
