> Derby doesn't support the entire range of valid (finite) values of the Java
> primitive types double/float in columns with SQL type DOUBLE or REAL. This
> appears to be a limitation that was introduced for compatibility with DB2.
> There have been some requests on derby-user that we lift this restriction.
> The restriction is enforced by the methods normalizeREAL() and
> normalizeDOUBLE() in org.apache.derby.iapi.types.NumberDataType.
