I can't say for everyone else, but I am very interested, but AFAIK there is a current development in this area on mpl, but I can be wrong,
No, you are correct, I just haven't gotten around to decimals yet.
but yor code looks promising. how well does it integrate with other mpl stuff?
I would like to know as well. I second the request to have it uploaded to <http://boost-sandbox.sourceforge.net/vault/>

Is there any interest in a compile-time meta-version of double?
Most definitely.
Syntax:
//Definition typedef META_DOUBLE(3.1415926535897932384626433) pi; //Or META_DOUBLE(3.1415926535897932384626433) pi_;
Yes, very compact.
//Mathematical operations typedef math::meta::add<pi,pi>::type pi2;
You can specialize the MPL plus metafunction so that it works on your double metatype. Or I can do that for you :)
//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.
Like I said, please upload to the sandbox vault so that we can examine the implementation. Cromwell D. Enage __________________________________ Do you Yahoo!? Make Yahoo! your home page http://www.yahoo.com/r/hs
