Cores: Tin Copper Silver Gold Decimal8 Decimal16
The Decimal cores natively implement the IEEE 754 decimal floating point formats. They are primarily useful in financial and economic computations, so this is their intended area of use: trading and banking and bookkeeping mainframes and servers.
Decimal8 implements only the 64bit decimal operations natively though.
