Very few developers truly understand floating point representation. Most think of it as base-10, and put in horrific kludges and workarounds when they discover it doesn't work as they (wrongly) expected. I shudder to think how many e-commerce sites use `float` for financial transactions!
So as far as I'm concerned, whatever performance cost these alternate methods may have, it would be well worth it to avoid the pitfalls of IEEE floats. Intel chips have had BCD support in machine code; I'm surprised nobody has made a decent fixed point lib that is widely used already.
