There's never any need to represent those separately, a single value

We believe there's no need for a multi-precision exponent, it would
only be a slowdown.

We believe there's no call to reallocate floats, an application will
want a particular precision and normally after just a few operations
the full size will be filled with data.

See "C++ Interface Internals" in the manual.  You need to read the
manual before asking the list.
