             Summary: Scaling float/double to bigdecimal/numeric is not always necessary
                 Key: TEIID-5692
                 URL: https://issues.jboss.org/browse/TEIID-5692
             Project: Teiid
          Issue Type: Quality Risk
          Components: Query Engine
            Reporter: Steven Hawkins
            Assignee: Steven Hawkins
             Fix For: 12.2


There is logic in the FloatingNumberToBigDecimalTransform to set the scale of the result bigdecimal to something representative of the scale of a float/double.  However the way that java represents precision/scale of small and large value - for example 0.0d becomes 0E-15 after the transformation - implies more precision or scale than expected.
