-- These testcases are experimental ('beta' versions), and they --
-- may contain errors. They are offered on an as-is basis. In --
-- particular, achieving the same results as the tests here is not --
-- a guarantee that an implementation complies with any Standard --
-- or specification. The tests are not exhaustive. --

-- This set of tests is for the four-byte concrete representation.
-- Its characteristics are:
-- 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
-- (mostly derived from the Strawman 4 document and examples)
