I have defined my own primitive type as below which works. import Base: >>, << primitive type UInt24 24 end >>(x::UInt24, y) = Base.lshr_int(x, y) <<(x::UInt24, y) = Base.shl_int(x, y) I then tried to define a masking operation using & the below works pretty well but I can’t figure out how to de…

I think I got a working solution. Just not sure if it’s the most efficient. z = UInt(16^5*15 + 16^4*15 + 16^3*15 + 16^2*15 + 16*15+ 15) unsafe_load(Ptr{UInt24}(pointer_from_objref(z)))
