-- 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: 2.59
-- This set of tests tests the extended specification 'round-to-integral
-- value-exact' operations (from IEEE 854, later modified in 754r).
-- All non-zero results are defined as being those from either copy or
-- quantize, so those are assumed to have been tested extensively
-- elsewhere; the tests here are for integrity, rounding mode, etc.
-- Also, it is assumed the test harness will use these tests for both
-- ToIntegralExact (which does set Inexact) and the fixed-name
-- functions (which do not set Inexact).
-- Note that decNumber implements an earlier definition of toIntegral
-- which never sets Inexact; the decTest operator for that is called
-- 'tointegral' instead of 'tointegralx'.
