The digits on that thread are not really random, though. Humans are terrible at emulating randomness.

At any rate, if you're willing to get your digits from an outside internet source, you can always get (almost) as many true random digits as you wish at random.org.

By the way, there's a very simple way to estimate how close you are to pi with these sums:

If the signs alternate and the numbers get smaller and smaller, then the error is - at most - the last number you added.

So:

1-1/3+1/5-1/7 is within 1/7 of the correct value of pi/4

x>1 doesn't give you an answer at all, because the numbers just get bigger and bigger.

And exponents are simply repeated multiplication, which is just as easy to do with fractions:

(1/2)^3 = (1/2)*(1/2)*(1/2) = 1/8

x=1 gives you the Leibniz Formula:

arctan(1) = 1-1/3+1/5-1/7... = pi/4

And I've already given my opinion about that one.

For x<1, the progress is much quicker because the series x,x^3,x^5,x^7 goes to zero fairly rapidly.
