Integer & rational arithmetic is guaranteed in Scheme and some other languages. In an R5RS compliant Scheme implementation you have for example (/ 5 7) => 5/7. (If only people get over their irrational fear of prefix syntax they would discover a great little language in Scheme.) But most prog. languages do not specify minimal required accuracy on standard floating pt. functions. May be because most language hackers are not numerical analysts!
