Comment (by rwbarton):

 Be aware (if you aren't already) that GHC does not do any management of
 floating-point control registers, so functions called through FFI should
 take care to clean up their floating-point state, otherwise the rounding
 mode can change unpredictably at the level of Haskell code.
