  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
