Re: How do coders handle 16-bit numbers?

I think I'm going to stick with what I've got. I've already started
writing a large piece of code which calls this subroutine and it seems
to work well. I have to admit I do not fully understand how the
routine works. I'd have to sit down with an abacus or something and
shift bits around before I could see how it actually works. but from
what I can see the max number of loops for the routine is 17. That
still eats some CPU time, but not as bad as making a loop which adds
the number to itself over and over, which is what I was doing before.

However, if somebody understands the routine and could tell me how to
optimize it for smaller numbers, that would be cool. Really I do not
need a 32-bit result. I only need a 16-bit result.
