Probably it will be emulation just like those precise N-bit types.

AFAIK x64 doesn't support those 64-bit/128-bit decimal types, and from 
reading about the format months back, it looks horrendous to do in software.

I think, if your translator has to provide emulations, then you have 
your work cut out. But I believe some of these features will be optional.
