The base of this idea is to add an undefined behavior clause if one writes

C++ using bit manipulation in a target machine that does not use binary

arithmetic in its arithmetic model. The bits value would represent a digit

in the numbering system or a q-bit if the system is a quantum computing

system. The best example I can think of is to have an arithmetic unit that

has base 10 as its numbering system. We still have types like int, long,

short, long long, unsigned int, unsigned long, unsigned short, unsigned

long long, float and double as well as value defined in cstdint but the

uint8_t would have value that range from 0 to 99999999 while on normal

hardware it would range from 0 to 255. endian would be useful regardless of

base as it would describe how the processor deals with multi-length words.

I am not sure if bit-shifting should be defined or not but if it is then

the bit shift sure work with the hardware base and not assume base-2.
