Many language implementations (including any for full Common Lisp) do support exact rationals, and people seem to like that. (They also support floating-point.) In the Lisp family, exact rationals are usually implemented and printed as simplified fractions; but using repeating decimals might be more useful. E.g. op:numeric-divide(5, 3) could return a decimal whose literal form might be "1._6_" where digits between _ and _ are infinitely repeating. -- --Per Bothner [email protected] http://per.bothner.com/
