The site seems to be asking for the internal floating point
representation. So it doesn't matter if it's IEEE 754, if the ints are
2-complements, or whatever. I used this code as a quick hack for one of
my programs, but I think it would work in this case. It should work for
any Storable type.
import qualified Data.ByteString as BS
binPut num =
fptr <- mallocForeignPtrBytes (sizeOf num)
withForeignPtr (castForeignPtr fptr) (\x -> poke x num)
BS.writeFile "/tmp/foo" (BS.reverse $ fromForeignPtr fptr (sizeOf num))
