Agree this could be beneficial to JDBC users.  To officially support this in 
JDBC would require an MR but as Douglas indicates  the work required to the 
JDBC spec would be minimal

JDBC would support this immediately. All it would take is the addition of a 
couple of lines in some appendices to require that conforming implementations 
of getObject(int, Class), setObject(int, Object, SQLType), etc support 
Decimal64 and Decimal128. No change to the API required. Driver vendors could 
add this support the instant the types are available, no need to wait for a 
change in the JDBC spec.

This would be a huge win for many Java apps. A large fraction of Java apps deal 
with money in some form. Binary floats are inappropriate for money and 
BigDecimal is too big and too slow.

Rather than waiting on Valhala I would prefer that this project be fast tracked 
and added to OpenJDK ASAP.

Thanks for doing this.

They'll find a natural home in JDBC, since SQL has a native decimal type.

As far as I can tell, scientific computation will make use of binary
floating point numbers for a long time. Decimal floating point numbers
are still limited to biz and fin applications.
