Speaking on behalf of Dejan, he expressed a wish to have such a type in D. (eg: such that assert(3.6 * 10 == 36.0) - which may not always be true on all architectures). As maybe a new backend type is out of the question. Perhaps we should create a new library type for the job - eg: _Decimal32, _Decimal64, _Decimal128. Thoughts? Regards Iain.
