This is precisely the cop out to avoid. Define your contexts.
Sure -- and J already gives you arbitrary precision rationals.
Decide how many digits is enough.
Taking my 1-cos 1e_6 example, here's an approach that might be adequate: 19j17":1-(2&o. t. i. 5x) p. 10x^-6 That said, I choose 5x for the number of taylor terms because it gives me the same displayed answer as arbitrarily more taylor terms... Also, this isn't going to work for %:
Or, alternatively: divide the current size of the universe by the Planck length. Use that many digits.
But note that the volume of the universe might need more digits than this to represent accurately. Context matters... -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
