-- [Previously called decimal32.decTest]
version: 2.59

-- This set of tests is for the four-byte concrete representation.
-- Its characteristics are:
--
--  1 bit  sign
--  5 bits combination field
--  6 bits exponent continuation
-- 20 bits coefficient continuation
--
-- Total exponent length 8 bits
-- Total coefficient length 24 bits (7 digits)
--
-- Elimit =  191 (maximum encoded exponent)
-- Emax   =   96 (largest exponent value)
-- Emin   =  -95 (smallest exponent value)
-- bias   =  101 (subtracted from encoded exponent) = -Etiny

-- The testcases here have only exactly representable data on the
-- 'left-hand-side'; rounding from strings is tested in 'base'
-- testcase groups.
