I've got a D programming language implementation of the General Decimal

ago but life got in the way, so I neglected it for a time. I now have the time
to finish it.
It uses std.bigint as the basis for the decimal numbers. I know there are plans
to bring BigFloat, decimal32, decimal64, and decimal128 numbers into D. The
completed* portion of the code fills the role of BigFloat (although I called it
Decimal), and I've got routines that encode/decode the dec32, etc. numbers but
they're not as far along as the arbitrary precision version.
I guess my question is whether I'm repeating work that's been done or is being
done in this area? If so, maybe I can lend a hand. If not, I'd like some
feedback on what is needed so I can work on the important things first.
Let me know what you think. At this point I'd settle for a go/nogo decision. We
can work bikeshed stuff later.
Go! We definitely want to get this into Phobos.
Thanks,
Paul
*"more or less complete" == It passes all the tests built in to the spec. No
logical operators or exp/ln/power. Still needs work. I suppose it could be called an
alpha version.
