version: 2.59

-- 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.
