Windows Calculator Bug1. Open calculator. 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: Windows Calculator BugHi; In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #3 20130524 00:09:01
Re: Windows Calculator BugIs it a different way of expressing Zero? 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: Windows Calculator BugFirst congratulations, half a zillion programmers will never know that in their entire life! A zillion math types do not believe it! They suspect that big bad Mi**8cro$oft is at it again. For once they are not to blame. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #5 20130524 00:40:35
Re: Windows Calculator BugIf it not a bug, whats it? 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: Windows Calculator BugIsn't this the precision stuff you always mention, bobbym? The limit operator is just an excuse for doing something you know you can't. “It's the subject that nobody knows anything about that we can all talk about!” ― Richard Feynman “Taking a new step, uttering a new word, is what people fear most.” ― Fyodor Dostoyevsky, Crime and Punishment #7 20130524 00:49:20
Re: Windows Calculator Bug
Computer math ≠ human math The order of addition can drastically affect the answer! 4) A computer can not subtract or multiply without possible disastrous error. 5) You never use the quadratic formula to solve a quadratic equation because on a computer it will give inaccurate results. 6) Newton's iteration though taught is rarely the best one for the job. 7) A computer can not compare theoretically equal quantities. and many more. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it.

Re: Windows Calculator BugSo, Is it possible that human beings will eventually develop something better?
Would you give an example? 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: Windows Calculator BugI remember the problem on calculating sqrt(3.0000000000000001)sqrt(3) you posed. Everything gives out 0 when the expression is evaluated directly, even M!

Re: Windows Calculator BugYes, without taking special pains on that one, subtractive cancellation will wipe out the answer. In mathematics, you don't understand things. You just get used to them.

Re: Windows Calculator Bug
they have a bug Hey. #13 20130526 02:52:43
Re: Windows Calculator BugOne way or another all math programs will do this, even Mathematica. In mathematics, you don't understand things. You just get used to them.

Re: Windows Calculator Bug
Thats Funny. Hey. #15 20130526 10:50:01
Re: Windows Calculator BugAnd sad.... 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: Windows Calculator BugIf you had to use binary, decimal, and floats all at the same time, you might come up with sqrt(4)2=8.1648465955514287168521180122928e39 as well. Notice the sqrt(1)1 is fine. Personally I prefer to use the Google DualMode Calculator app in Google mode, which gives sqrt(4)2=0. #18 20130611 17:24:07
