That adds requirement that they be IEEE 754 formats though. While I don't
know platform using any other format these days, I don't think C++ requires
that just as it does not require two's complement for signed integers.

So there would have to be one set of typedefs for just size/precision and
another for the IEEE 754 standard formats.
