actually it would have to be
int(ln(10)/ln(pi*pi)*100) % 10

% = mod for those who don't know.

anyway, i suppose i'll answer. 0.

I think I have it but I can't post an answer to this question I asked the question before this

I think I have it but I can't post an answer to this question

is it different from 0 1 or 7? i'm fairly confident 0 is the answer, graph misused my expression and i'm unsure what sir did.

[ruler501]

I don't think its any of those three. just work it out by each place starting with what would be the tens but is now the pi^2 then keep working down till you get to the second decimal place or the pi^-4
calcdude84se told me I have the right answer Now I'll work it to the 5th decimal place

[calcdude84se]

Ruler PM'd me with his answer and it is correct. Good luck to the rest of you!

[Runer112]

I got 2.

[jnesselr]

Doing the math again, I believe it is around 10.128

Whoa, ninja'd by 3 seconds.

[calcdude84se]

Runer and Graph are correct.
However, since Runer got it first, it's his turn to ask.

BY 3 SECONDS!

Fine, I look forward to runner's challenge. ;-)

[ruler501]

I got 10.12999999...
how'd you get the 10.128?

freaky I posted at the same time as nemo

[nemo]

ohh. like the number system pi squared... that would've been helpful to know.

i'm curious as to what runer will come up with

[jnesselr]

I got 10.12999999...
how'd you get the 10.128?

I actually rounded after I knew I found the terminating digit.  10.129999... still has 2 as the 2nd digit.

[ruler501]

Why'd you put 8 as the third decimal digit though? that was what I was asking

Because I did this on my calc, and it started doing weird results the smaller the number. So like 5.68e-22 or whatever.  I could have continued, just chose not to.  8 is probably not accurate.  It would get more accurate, the more accurate pi is.  I could write a program on my computer to do this out to 1000 decimal places.  But I only need 2.

[calcdude84se]

The third digit is indeed 8, as verified by a calculator on a PC, but that's irrelevant
