Please write out 0.99999... fully and I will be satisfied.

Since there is no such thing as infinity, and by extension infinite 9's, let's just save the effort and pretend you guys didn't make such asses out of yourselves.

Watch my video narc. And learn. Instead of being stubborn and just posting the same bullshit. Provide some actual feedback on what you observed and then tell me the calculator is wrong.

your calculator is wrong

Full disclosure: I haven't watched your video yet. However:

1. Arguing that the behavior of a certain calculator shows something doesn't actually prove anything. You could hack your calculator's software, you could alter (photoshop) the images and that, in itself wouldn't show anything

2. Calculators, like all human-created machines have internal representations of human concepts. And those, by themselves, could be wrong. Remember how certain Intel processors were shown to calculate certain formulas wrongly?

3. All other precepts being right (no alteration of the video, and no alteration of the software and the software itself being correct), it could

still show the wrong outcome. If the premises of its creators were wrong (i.e., if one of them didn't know the concept of Repeating Decimals), it still could show results that wouldn't represent the "correct" mathematical outcome

It seems like your calculator works right. However, look at the "google code jam" that took place, recently. You were asked to give the result, if I remember it correctly, of a simple operation: ((3 + 2^(1/2))^n) mod 100 . (the mod operation gives us the remainder of an operation. 199 mod 100 = 99)

Simple, isn't it? Well, calculate the result using your machine, when n=1,000,000,000. Try doing the same by hand. The result of your machine is, quite probably 00. The correct result is completely different. A calculator, by itself, takes shortcuts. Even the best of machines tries to represent big numbers as best it can. And it still will err when the numbers are big/small enough.
