+version: 2.57
+
+-- 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.
