version: 2.58
-- This set of tests is for the eight-byte concrete representation.
-- Its characteristics are:
--
-- 1 bit sign
-- 5 bits combination field
-- 8 bits exponent continuation
-- 50 bits coefficient continuation
--
-- Total exponent length 10 bits
-- Total coefficient length 54 bits (16 digits)
--
-- Elimit = 767 (maximum encoded exponent)
-- Emax = 384 (largest exponent value)
-- Emin = -383 (smallest exponent value)
-- bias = 398 (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.
