-- 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
