Decimal/Currency Type

[Zane via Digitalmars-d]

There has been a question or two about this before, but I really 
don't feel there has been a reasonable answer (or I have missed 
it).

I am wondering if there is a fixed decimal type, either built-in 
or implemented in Phobos (similar to python's "Decimal" or Java's 
"BigDecimal").

Previous posts suggested using a long and keeping track of the 
decimal point, but there are a few problems with that. First, 
arithmatic with, or assignments from, other  types wouldn't 
translate properly (the built in types have no awareness of the 
decimal point location associated with the long). Second, if 
using for currency as an example, I could probably get by with 
long if only tracking cents, but what if I wanted to track 
thousandths of a cent or more? That wouldn't leave me with much 
place values to track large dollar amounts.

Is there such a thing build into D? If not, is there any plans to 
add it? It seems like this would be something needed by many 
applications (especially anything dealing with currency).
