My personal roadmap would be the following:

1) big int - this is what I am currently working on

2) rational: boost::rational exists already

3) fixed point

4) floating point with fixed, but aribitrary precision

3 and 4 hopefully can be based on the currently growing
big int class.

Other types like dimensioned quantities, std::complex,
quaternions, polynomials etc.
are more or less independent from that roadmap
and might probably have a template parameter for
the respective numeric type.
