 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.

 27-- This tests toIntegraExact, which may set Inexact
