There's bit fields in C++. https://en.cppreference.com/w/cpp/language/bit_field https://en.cppreference.com/w/cpp/language/bit_field If you don't need the full precision or range of a 64-bit integer you can pack multiple of them together to get multiple integers transferred in a single cache line read. Compressing in this manner also means you are more likely to get a cache hit.
