Loss of precision with Oracle

[GoogleCodeExporter]

As explained in http://docs.oracle.com/cd/E19159-01/819-3672/gbxjk/index.html 
the JPA mapping to Oracle maps float and double onto NUMBER(19,4). This gives 
only 4 digits after the decimal point - which is very bad if you want to store 
small numbers! MySQL does it sensibly and maps double to double.

Ideally it would map simply to a NUMBER - which I have not been able to do. 
However with an appropriate annotation I can make it map onto NUMBER(38, 127) 
which is equivalent to simply NUMBER. This will be addressed in 4.3.0 as it 
will require an update script to change existing schemas.
