There are older languages just waiting for the people who dislike IEEE 754 floats to notice them too, like Common Lisp and Scheme. They have a numeric tower which includes both rational and complex rational numbers: > (+ 5/3 4/5) 37/15 > (expt #C(0 1) 2) -1 > (expt #C(3/2 1/2) 2) #C(2 3/2) And of course they all support arbitrary precision numbers as well: > (complex (fact 10) (fact 20)) #C(3628800 2432902008176640000) > (/ (complex (fact 10) (fact 20)) 29) #C(3628800/29 2432902008176640000/29) Composition is a wonderful thing.
