* JDBC and numeric datatype...

Can someone suggest the correct way of dealing with the NUMERIC data type
through JDBC? The attribute in question is a NUMERIC(10,2) (currency)...
We're thinking of just using a float to handle it... Since this type can be
much larger than we're using, what should be used in those cases???
Thanks.
S.

Look for some arbitrary precision math library to deal with
it. NUMERIC in PostgreSQL is an exact numeric data type, a
strict requirement when dealing with monetary values in
bookkeeping systems. A single conversion to and back from
floating point violates this requirement already.
