5-- Please see the document "General Decimal Arithmetic Testcases" --

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

22-- This set of tests is for the four-byte concrete representation.
23-- Its characteristics are:
24--
25-- 1 bit sign
26-- 5 bits combination field
27-- 6 bits exponent continuation
28-- 20 bits coefficient continuation
29--
30-- Total exponent length 8 bits
31-- Total coefficient length 24 bits (7 digits)
32--
33-- Elimit = 191 (maximum encoded exponent)
34-- Emax = 96 (largest exponent value)
35-- Emin = -95 (smallest exponent value)
36-- bias = 101 (subtracted from encoded exponent) = -Etiny
