 20version: 2.58
 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'.
