Greetings to everyone,
If we take a processor with 16bit precise ALU and try to compute a
factorial (n!) form 2^80, what happens with ALU then? To be more precise,
does ALU width (precision) limits it from computing numbers higher than it
can allocate and how (if?) does it impacts performance of integer
computing? In other words, how come it is possible to compute very large
number if ALU is not precise enough for them (or my calculator is being
dishonest).
I hope I made my point clearly enough. Thanks in advance.
