version: 2.59

-- This file tests that copy operations leave uncanonical operands
-- unchanged, and vice versa

-- All operands and results are decQuads.
extended:    1
clamp:       1
precision:   34
maxExponent: 6144
minExponent: -6143
rounding:    half_even

-- Uncanonical declets are: abc, where:
--   a=1,2,3
--   b=6,7,e,f
--   c=e,f

-- assert some standard (canonical) values; this tests that FromString
-- produces canonical results (many more in decimalNN)
