"must be builtin in any modern language" – which modern languages 
actually have decimals as a built-in type, and what is your 
rationale against having them as a solid library implementation? 
It seems like it would only be interesting for a very fringe 
sector of users (finance, and only the part of it that actually 
deals with accounting).
