I was lying down going to sleep and I realized I shouldn't use so many digits, was thinking about binary, 0 and 1, octal, 0-8 and so forth so it must be only 0,1,2,3 for PI. So what would 1223.22 be in PI?*Originally posted by Fat Lady***Surely you can only use the digits 0, 1, 2 and 3 in base pi?** - 08 Dec '08 09:48A arbitrarily chosen base, integer, rational, end even real bae, never done that, very interesting.

The formula goes: sum{a(i)*b^i}

where i is an integer from low to high,

and b is a real base > 1, I suppose?

It doesn't make sense if b < 0, and definitely not when b=1, correct?

Can we use the formula to construct any real number?
