Perhaps you are thinking of this, which means something entirely
different?
(exact? 2/3) => #f
(exact? 37287.2983) => #f
Why say 'chicken doesn't have rationals', when it has a perfectly
satisfactory implementation of rationals, that is 100% standard
compliant except for three easy-to-write functions being missing?
What it doesn't have is *exact* rationals.
