> In finite precision arithmetic "multiplying by pi or e" makes no sense. And all arithmetic is finite precision. Yes. that's kind of my point: Either you have a finite precision cutoff and lose accuracy, or the memory used for your arbitrary precision representation blows up to incredibly large values (transcendentals will do this to you quickly), or a combination of the two.
