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...
