-- 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.
