I've tried to use your simple "general use" example in your documentation with
MS Visual studio 9.0

Sadly it fails to compile with an Internal compiler error :-(

1>Compiling...
1>demo_unbounded_int.cpp
1>i:\trunk\boost\mp_math\mp_int\detail\string_conversion_constants.hpp(44) : fatal error C1001: An internal error has occurred in
the compiler.

'boost::mp_math::detail::max_power<MpInt,Base>' being compiled

This is a bit of a showstopper ;-)

Or am I doing something silly?

Any suggestions about what to try changing?

Thanks

I'll also need these for sure so it would be nice if they were added to the next release:
