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

20version: 2.59
21
22-- This set of tests tests the extended specification 'round-to-integral
23-- value-exact' operations (from IEEE 854, later modified in 754r).
24-- All non-zero results are defined as being those from either copy or
25-- quantize, so those are assumed to have been tested extensively
26-- elsewhere; the tests here are for integrity, rounding mode, etc.
27-- Also, it is assumed the test harness will use these tests for both
28-- ToIntegralExact (which does set Inexact) and the fixed-name
29-- functions (which do not set Inexact).
30
31-- Note that decNumber implements an earlier definition of toIntegral
32-- which never sets Inexact; the decTest operator for that is called
33-- 'tointegral' instead of 'tointegralx'.
