PI is not rational, so cant be expressed as x/y for any integers x and y.

Thanks - made me pull my socks up - was looking scruffy. True 22/7 is also an approximation - but is more easy to use in practical applications (for measuring / building the imperial system IS easier than decimal).

In absolute terms I see what you are saying... how many decimal places to date have now been calculated? And it goes on.........

Now that we've solved that one, shall we try the Monty Hall problem?!

22/7 people disagree with the other 6/7 but anyhoo: Why don't you just work in units of pi. Then 1 = pi, 2 = 2pi, and so on.

I hate the pies. Go Blues! The only way is up, baby, for you and me now...

What were we talking about again?
Oh yeh, maths.

Well then. That's nice dear.

Stu, are you married to a mathematician?

Ha!
A nurse actually.

I say "I'm sick", and she says "get over it".

.99999 recurring is not an exact number but depending on how many decimal places you take it gets closer to 1 but never 1.

I concur
