[Greg Chicares]

branch: master
commit f576a4b7e82a0e716bd730d8829d84ce11c3a296
Author: Gregory W. Chicares <gchicares@sbcglobal.net>
Commit: Gregory W. Chicares <gchicares@sbcglobal.net>

    Augment unit test
    
    Motivation: Interpolations such as these arise when bounds are extremely
    large, and can lead to catastrophic cancellation.
