-- 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
-- These tests require that implementations take account of residues in
-- order to get correct results for some rounding modes. Rather than
-- single rounding tests we therefore need tests for most operators.
-- [We do assume add/minus/plus/subtract are common paths, however, as
-- is rounding of negatives (if the latter works for addition, assume it
-- works for the others, too).]
--
-- Round-for-reround (05UP) is tested as a separate block, mostly for
-- 'historical' reasons.
--
-- Underflow Subnormal and overflow behaviours are tested under the
-- individual operators.
