Really interesting article! I always believed that doing floating-point arithmetic correctly was a tricky business - now I am convinced... ;) Good to know for us that OCaml is at least extremely close to the IEEE 754 standard, though there is still criticism in this article that is relevant for OCaml, too (e.g. things like non-availability of extended double-precision; lack of operator overloading; etc.). Luckily, my needs for numerical computation are not this high...
