That is internal to the multiplication method black mox. Like in present day ram-memory storage in multiples of 8 bits is more efficient, but that should be internal to the storage methods. Perhaps using present day microcode some special embedded code can be very efficient and the programmer should be aware of that, like he should be aware of parallel execution in multicore processors and prefetching of memory-values on a probablistic theory. However in general terms, binary is the preferred way of storing en computing at the moment, and doing those WITH JAVASCRIPT in variable bases is ludicrous. Making input and output conversion algoritms are quite interesting and feasable, but let us keep that apart from storage and operator functions. -- Evertjan. The Netherlands.
