[boost] meta-double

Is there any interest in a compile-time meta-version of double? Syntax: //Definition typedef META_DOUBLE(3.1415926535897932384626433) pi; //Or META_DOUBLE(3.1415926535897932384626433) pi_; //Mathematical operations typedef math::meta::add<pi,pi>::type pi2; //Evaluation: assert(META_DOUBLE_EVAL(pi2)==3.1415926535897932384626433*2); This implementation uses two ints to represent the decimals, and a short to represent the exponent. It has been tested on VC7.1,VC8.0 beta and GCC3.2 Regards, Peder
