[Haskell-cafe] Binary IEEE floating point format for AMQP

I'm working on an implementation of the framing layer for AMQP (www.amqp.org). I almost had 0.9 finished when I found they had released the spec for 0.10, so I have to redo quite a lot of work. Amongst the new features of 0.10 are wire formats for floating point. These are the 4 and 8 byte IEEE formats. * Is there a principled way of converting a Haskell Float or Double (or Rational, for that matter) to and from IEEE format? * Since many computers use IEEE format natively, is there a quicker way of doing this on those architectures?
