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.

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.

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

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

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

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

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.

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