| -- 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. -- | |

| -- This set of tests tests the extended specification 'round-to-integral | |
| -- value' operation (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. | |
| -- Note that 754r requires that Inexact not be set, and we similarly | |
| -- assume Rounded is not set. | |
