Pick a finite precision sufficient for your needs and wrap in (with-precision ...). Take care about returning lazy sequences containing bignum division results though; you may need to use the odd (doall ...) to force sequences before they leave the scope of the with-precision. -- Protege: What is this seething mass of parentheses?!
