9-- These testcases are experimental ('beta' versions), and they --
10-- may contain errors. They are offered on an as-is basis. In --
11-- particular, achieving the same results as the tests here is not --
12-- a guarantee that an implementation complies with any Standard --
13-- or specification. The tests are not exhaustive. --

22-- This set of tests tests the extended specification 'round-to-integral
23-- value' operation (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.
26
27-- This tests toIntegraExact, which may set Inexact
