|
|
-- 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'.
