of tests tests the extended specification 'round-to-integral 237db96d56Sopenharmony_ci-- value-exact' operations (from IEEE 854, later modified in 754r). 247db96d56Sopenharmony_ci-- All non-zero results are defined as being those from either copy or 257db96d56Sopenharmony_ci-- quantize, so those are assumed to have been tested extensively 267db96d56Sopenharmony_ci-- elsewhere; the tests here are for integrity, rounding mode, etc. 277db96d56Sopenharmony_ci-- Also, it is assumed the test harness will use these tests for both 287db96d56Sopenharmony_ci-- ToIntegralExact (which does set Inexact) and the fixed-name 297db96d56Sopenharmony_ci-- functions (which do not set Inexact). 307db96d56Sopenharmony_ci 317db96d56Sopenharmony_ci-- Note that decNumber implements an earlier definition of toIntegral 327db96d56Sopenharmony_ci-- which never sets Inexact; the decTest operator for that is called 337db96d56Sopenharmony_ci-- 'tointegral' instead of 'tointegralx'. 347db96d56Sopenharmony_ci
