I think we're in agreement. I basically said there'd be no point unless for some reason you wanted to describe radians as whole numbers.
Otherwise, baseπ doesn't make any sense, especially since there's no unambiguous way to define a constant interval between irrational integers (a contraction of terms, I know).
My main point was that there's no way to have a baseπ numeral system, and even if you could it would have next to no practical value.
