"Some time ago" is 3 years since the last post here so I assumed the project 
was dead. 
But how much difference can it be? Decimal math either uses fixed precision  
or floating point and then rounding can either be tied to type or operation. I 
choosed fixed precision and rounding based on type. If I understood correctly 
Bill Seymore used fixed precision and rounding on operation.

The rest is just about interface and there I'm open to suggestions on what 
should be member functions and what should be free functions. Currently my 
interface is rather bloated and everything is member functions.

Depends on what you mean. My decimal type will probably be obsolete when these 
new types arrive but the money type shold be able to use them with a wrapper 
for construction and extraction.

Also, I have tried to look at the committe's work but don't really understand  
how rounding will work with these new types.
