Subject: Re: [boost] Name and Namespace for Potential Boost Extended Floating-Point

I'm leaning towards ...
namespace boost {
namespace mpfp { // multi-precision floating point
class real;
class complex;
} // mpfp
} // boost
Also, what does it mean for an integer type to be *multi-precision* ? Is it
something along the lines of BigInt ?
