-- Please see the document "General Decimal Arithmetic Testcases" --

-- --
-- These testcases are experimental ('beta' versions), and they --
-- may contain errors. They are offered on an as-is basis. In --
-- particular, achieving the same results as the tests here is not --
-- a guarantee that an implementation complies with any Standard --
-- or specification. The tests are not exhaustive. --

version: 2.58
-- Note that we cannot assume add/subtract tests cover paths adequately,
-- here, because the code might be quite different (comparison cannot
-- overflow or underflow, so actual subtractions are not necessary).
