I'd like to direct folks' attention to the IEEE-utils package on hackage
[1], which Matt Morrow started and I have made a few additions to. There are
bindings to set and check the rounding mode, as well as check and clear the
exception register. On top of that I've built a very experimental monadic

Not sure. My doubts are mainly on interference between threads. If a thread
can keep its FP sta

I'm deviating from the thread's topic, but I tend to agree with this one.
Maybe not IO directly, but some kind of STM-style monad, at least (that is,
FP operations are composable but
