No, not from memory. From Google.

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 ;) :lol:

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.

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

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.....

:lol:

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

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!

Where are you getting your numbers?
