1) Integer maths is (esp. division) is faster than floating point maths. Much of it is literally one clock cycle.
2) No rounding errors.

Voting tabulators should not only use integers but also ECC memory and other hardware that has been certified for banking.

Most math period is one cycle. Hell, modern CPUs can do two math ops in one cycle on the same piece of arthritic hardware.
there is literally a chart on that page that shows that it can indeed be faster, and it didn't even make use of SSE or AVX( the-O3 doesn't use AVX or SSE unless you also set that flag to be true).
Division is even consistently faster bar on the Bulldozer based CPU.
So you never want the tabulation software to give a vote percentage? As in, you don't want it to report "52% of people voted for so and so)?

No, tabulating software should not have any reports on it. That is the job of an entirely different project.

So you want to send the number to another machine and then convert it to a floating point and then do the required math to get a percentage?

YES.
A voting machine should do only one thing: Count votes. Any other software on it is suspicious.
Probably correlation: the people who have internalized just how terrible the democrats are are also the most motivated to do something about it, and thus vote, while the people who think the democrats aren't terrible and things are mostly working or think both are equally terrible, aren't motivated to vote, even if they think it works.
If you could poll Germany in the late 1930s, the parties (Nazis and Communists) who wanted to disolve democracy where probably more enthusiastic to vote to dissolve Weimar than the liberals were enthused to vote to preserve Weimar.

So you want to introduce possible rounding and conversion errors?

You clearly don't understand what you are talking about. The vote counts are what the tabulating machine should be calculating, storing, and providing to the next link in the chain of custody. The vote counts are the only thing that matter. Percentages can calculations are so trivial they can by done by hand using the vote counts.

"BEEP!"
last time I said this people wondered if I was a glowy, but I think this bears repeating. Can we stop with this bathtub revolutionary nonsense? For all your (several people not just one) bellyaching about how "The only way to secure our country is to arm up and storm the bastille." we all know you're not going to form some right-winged ANTIFA so knock it off already. this is in my opinion childish and frankly an hour of work with your hands is 10x more valuable than the blaring of a thousand bullhorns and frankly I think all this screaming into the abyss is making some of us literally go insane. (Lord Inviticus and FriedCFour come to mind)
At this point I'm afraid most of us will kill over from stress or worse self-terminate long before any brown or red shirts do us in.

Are you joking? The description of the chart is lower is faster. Short, long, and long long have consistently faster or equal speed for addition, subtraction, and multiplication speeds than floats or doubles. Poiting out that division is an outlier doesn't support your case, it harms it.
Also, why would a voting machine need to do multiplication or division?
Unless of course said mathematical functions are tied to way to mess with the votes by treating some votes as having more 'weight' than others.

Speed doesn't matter here, accuracy does. This Is why I want ECC memory.

If speed did matter you aren't going to gain anything by trying to optimize something like:
Code:
incl 4(%eax)when adding a vote to a specific candidate's tally. The time consuming part is everything that happens before that instruction to add one to what's stored at a specific memory location.

In regards to our voting tech, I don't give a crap about process speed. I only care about accuracy.

It needs to be completely transparent as well.
None of this bullshit where private companies make sure no one can see the software or audit them. Absolute insanity.

Once again, I even pointed out that it was probably just a guy using the default variable type and said "fuck it" about changing things.
I agree, keeping the source code closed like they are is what's suspicious... not a fucking decimal place.
