version: 2.59
-- 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.
-- This tests toIntegraExact, which may set Inexact
