Craig Russell commented on JDO-206: ----------------------------------- The issue here is that Derby treats the FLOAT data type is used to represent both single- and double-precision floating point numbers. To get a single-precision value in the database, you have to use either REAL data type or specify a length on FLOAT. Everywhere we really want a 32-bit floating point number to be stored, we need to specify REAL or FLOAT(24) as the column type. > JDOQL test NotEquals comparing floating point numbers > ----------------------------------------------------- > > Key: JDO-206 > URL: http://issues.apache.org/jira/browse/JDO-206 > Project: JDO > Type: Bug > Components: tck20 > Reporter: Andy Jefferson > Assignee: Michael Bouschen > Attachments: JDO-206.patch > > The current TCK test (carried over from JDO 1.0) for NotEquals, uses != > operator on floating point numbers. This is not a good practice, and is > unreliable. Its probably the case that the Equals test uses == on the same > content, which also is not a good idea (as noted in the latest spec).
