Good shout Brian, Pi to how many places?

1000

[Labarum]

True on both points Nick,

Brian?

No, not from memory. From Google.

[Beechwoods]

You blew it Brian! You could've lied and would forever more been remembered as the man who knew pi to 1000 places off the top of his head! Ah well

[Labarum]

Can't lie. I'm a clergyman. Haven't you Googled my screen name?

(And no one would have believed me.)

3.142 is as far a my memory takes me (O, those wretched log tables!)

1.414 for sqrt 2

2.71 for e

But hey, that's not bad: I have done no Physics or Electronics Theory since 1970.

It's worth the extra post if it was typed from memory!

PS. You promised us a random number. That was the least random number ever

Just seen your PS - PI is an irrational.

I think if you start at a random point in PI's decimal places, the digits will follow in random order - or at least as good as most other means of generating a random series.

But I haven't done any Maths since 1970 either.

Was that a "Yah Boo Sucks"?

Well, if I knew what one of those was.....



I always remember Pi as 3.1417, can never remember further though, and that's not even correct anyway!

At grammar school in Derby (up to A-levels in 1969), we were always told that Pi was 22/7. When I mentioned this to a Maths teacher here in Spain she was most impressed, saying that was the only true answer for a value of Pi. Bloody decimals.

22/7 is an approximation. PI is an irrational. It cannot be expressed as the quotient of two integers.

And it's also not correct (22/7), if 22/7 is expressed as a decimal it is in fact 3.1428. Pi is stated as being 3.14159 and not 3.1417 as I thought, even rounding up would make it 3.1416 so I'm well out. I do know however that Pi comes from the latin for perimeter which is written as: περίμετρος

Man, this is what I call thread drift!
