Global Moderator Joined: Dec 2006 Posts: 20,927 Thanks: 2205  I was asking you about your initial wording (not making a point). Can you answer in relation to that, bearing in mind that your reason(s) for the wording of your opening post couldn't have been based on replies that hadn't been posted at the time?

'I don't know' doesn't appear in the OP and the whole sentence you quoted only the end of was; 'I refuse to accept that a number can be reoccurring and that this evidences the fact our numbering language is fundamentally flawed.' The fact a number can be reoccurring in our recognised mathematically language is not unchecked grounds.

You yourself stated that the mathematics community was more open to questions than that of theology. I'm not so sure. If maths is a system that exists outside of real world situations aren't mathematicians just advanced coders? Now that is inflammatory!

I didn't state that 'I don't know' appeared in any post. However, your later reference to yourself as agnostic suggested that 'I don't know' was your default position. You referred to something (it's not clear what exactly) as a fact without having given any clear reason for using the word 'fact'. Also, you used the word 'fundamental' without giving any reason for doing so. What adjective would you use to describe a flaw that isn't fundamental and what determines which adjective is appropriate?

No. Mathematicians aren't coders  advanced or otherwise. It seems to me a bit like suggesting that car mechanics are just advanced drivers.

How can you not understand the difference between a Mathematician's concept of 1/3 as being an exact quantity no matter the number of decimal places and the Scientist's concept of measuring 1/3 only up to a given precision? If decimals bother you, then use 1/3. If exact numbers bother you, then use 0.3333333333. This is a nonissue. And, really, the whole even/odd thing? How can this possibly be an actual issue? You've been confrontational about this whole thread. You aren't really asking anything and don't seem to be doing much listening when others make a statement unless you feel you can twist it into something you believe is going to support your (as I said before) vacuous OP. Just as a Troll would do. Quote:
Someone please close down this thread. And with that I'm out and to paraphrase, in terms of religion, I'm shaking your dust off my feet. Dan Last edited by skipjack; January 22nd, 2019 at 08:43 AM.

Ok let me straighten this out. I have no mathematical education beyond GCSE’s as I’m sure is abundantly evident. I’m a 35 year old Project Manager and have never needed a higher understanding of math vocationally. For me it’s about curiosity. The recurring decimal is the itch that I can never quite scratch. It frequents my dreams and invades my meditations. It’s the blot on my copy book, the fly in the ointment, the Ringo to my Paul McCartney. My post wasn’t meant to antagonize, insult or perturb. It was more of a ‘hey – what gives?’ I just cannot sate the feeling that the mathematics that underpins so many of the foundations on which we build our lives, so harmoniously accepts this troublesome and unsolvable conundrum. 1/3 isn’t 0.3333. They are not the same – they are not factually correct. They are approximate. 0.3333 is not a real number, it’s not measurable, it’s not accountable, in pure terms it’s fantasy. It’s a number that has no end, it’s an impossible event. Yet if I ask someone, ‘hey man, nice brogues, what’s ten divided by three?’ they will surely retort ‘ Why it’s 3.3333 recurring my good man’. What filth is this number! That’s why the language of math puzzles me. The most erudite minds can easily stomach the implausibility of its mechanisms. It feels like a giant rouse that everyone’s in on. I have learnt several languages (badly) and read music and each have their own foibles and curiosities. But not claim absoluteness like math does. I just don’t get how people can be satisfied whilst the recurring decimal is always there, mocking, taunting, existing.

I shall try to answer. No one says that $\dfrac{1}{3} = 0.3333.$ People do say $\dfrac{1}{3} = 0.3.....$ What does that mean? It means that it would take an infinite number of digits to express one third in decimal notation. Thus, for practical purposes, decimal notation is not exact with respect to fractions. But decimal notation of fractions is not fundamental to math. It can be dispensed with entirely. And in terms of practical applications of math, we can get a decimal expression for one third that has no observable error in practice. Decimal representation of fractions is a useful approximation for some practical purposes, nothing more.
