Indeed, who knows? But the devil is in the details, and I don't see any practical (reasonable performance) way forward without lookup tables, and lookup tables for 32 bits will be *huge*. IEEE floating point has its flaws, but at least it's clear how to implement it.
Having said that, I hope he is able to come up with a solution. But right now it's definitely not ready for prime time.
One amazing feature of POSITs is that you can do an FFT and then run the results through the reverse FFT and get back, bit for bit, exactly the input you started with. Try doing that with floats.
