Pi

What is the 3,183,247th digit following the decimal point in the value of pi?

There might be a fair amount of money riding on it so proof would also be required.

3

[4getmenot]

I still remember little ditty I made up to remember the numbers of pi
'How I like quick microwave to fasten china meal'

[bibblebub]

And your proof that 3 is that digit is?

[4getmenot]

I dont know, I never got that far with ditty

[bibblebub]

doesn't everyone know:-

Sir, I bear a rhyme excelling
In mystic verse and magic spelling
Celestial sprites elucidate
All my own striving can't relate

[4getmenot]

Oh bum, my meal bit must be wrong

I've always found it easier to remember the actual digits of Pi (up to a reasonable number of places) than to remember the mnemonics! ;-)
(I used to be able to rattle off the first fifty or so digits but my 'little grey cells' aren't quite as good as they used to be!)

There are plenty of downloadable versions of Pi (from reputable sources, such as leading universities) providing well over the number of places you require but, if you want 'proof', to what extent would you trust the methodology used for the calculation? For example I could produce a computer program, within a few minutes, that can produce an increasingly accurate estimate for Pi but that program would rely upon all random numbers generated by the computer being genuinely random (and not the pseudo-random numbers which most computers actually generate).

I must admit that I used that mnemonic that I posted as a step to remembering the 20 digits after the decimal point, and the occurrence of the triplets 535, 979 and 323 definitely help. One can occasionally get a wow! reaction by coming out with that number sequence unexpectedly.

And I just thought of the number 3,183,247 at random... or is it random?

I only ever got taught the first seven numbers after the decimal. Mnemonic, (of course) 'how I wish I could calculate Pi'

You can't supply a proof except by doing the calculation. Depending on how much money is riding on this and If you would split the money with me 50-50 then I might consider spending the rest of my life calculating it for you. Joking of course.

According to this site the 3,183,247th digit following the decimal point is a 1

Phew!- at least you didn't tell me to google it, factor30.

I was only kidding when I posted this question. The only money riding on it would be if I chose it as a lottery number - but I don't do the lottery.

The site I used above is good. For example it shows that the string 99999999 occurs at position 36,356,642 counting from the first digit after the decimal point.

I've bookmarked it amongst my maths references but it does leave me wondering if I'll ever make use of it in future.

Handy if you ever want to work out the area of a circle very very accurately!

[bibblebub]

or if the circle is humongously big

I think there is a 3 in pi somewhere
