version: 2.59
-- This file tests that copy operations leave uncanonical operands
-- unchanged, and vice versa
-- All operands and results are decDoubles.
precision: 16
maxExponent: 384
minExponent: -383
extended: 1
clamp: 1
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)
