+ # then:
+ #
+ # (1) if xc != 1 then for the result to be representable we

+ # if |y| <= 1/nbits(xc) then xc < 2**nbits(xc) <=
+ # 2**(1/|y|), hence xc**|y| < 2 and the result is not
+ # representable.

+ # |y| < 1/|xe| then the result is not representable.
+ #
+ # Note that since x is not equal to 1, at least one of (1) and
+ # (2) must apply. Now |y| < 1/nbits(xc) iff |yc|*nbits(xc) <
+ # 10**-ye iff len(str(|yc|*nbits(xc)) <= -ye.
+ #
+ # There's also a limit to how large y can be, at least if it's
+ # positive: the normalized result will have coefficient xc**y,

+
+-- This file tests base conversions from string to a decimal number
+-- and back to a string (in Scientific form)
+
+-- Note that unlike other operations the operand is subject to rounding
+-- to conform to emax and precision settings (that is, numbers will
+-- conform to rules and exponent will be in permitted range). The
+-- 'left hand side', therefore, may have numbers that cannot be
+-- represented in a decDouble. Some testcases go to the limit of the
+-- next-wider format, and hence these testcases may also be used to
+-- test narrowing and widening operations.

+-- This file tests that copy operations leave uncanonical operands

+-- Uncanonical declets are: abc, where:

+-- c=e,f
+
+-- assert some standard (canonical) values; this tests that FromString
+-- produces canonical results (many more in decimalNN)

+-- Note that we cannot assume add/subtract tests cover paths adequately,
+-- here, because the code might be quite different (comparison cannot
+-- overflow or underflow, so actual subtractions are not necessary).
+-- Similarly, comparetotal will have some radically different paths
+-- than compare.
+
+-- All operands and results are decDoubles.

+
+-- 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.

+-- These tests comprese three parts:
+-- 1. Sanity checks and other three-operand tests (especially those
+-- where the fused operation makes a difference)
+-- 2. Multiply tests (third operand is neutral zero [0E+emax])
+-- 3. Addition tests (first operand is 1)
+-- The multiply and addition tests are extensive because FMA may have
+-- its own dedicated multiplication or addition routine(s), and they
+-- also inherently check the left-to-right properties.

+version: 2.56
+
+-- This set of tests tests the extended specification 'round-to-integral
+-- value-exact' operations (from IEEE 854, later modified in 754r).
+-- All non-zero results are defined as being those from either copy or
+-- quantize, so those are assumed to have been tested extensively
+-- elsewhere; the tests here are for integrity, rounding mode, etc.
+-- Also, it is assumed the test harness will use these tests for both
+-- ToIntegralExact (which does set Inexact) and the fixed-name
+-- functions (which do not set Inexact).
+
+-- Note that decNumber implements an earlier definition of toIntegral
+-- which never sets Inexact; the decTest operator for that is called
+-- 'tointegral' instead of 'tointegralx'.

+version: 2.56
+
+-- This file tests base conversions from string to a decimal number
+-- and back to a string (in Scientific form)
+
+-- Note that unlike other operations the operand is subject to rounding
+-- to conform to emax and precision settings (that is, numbers will
+-- conform to rules and exponent will be in permitted range). The
+-- 'left hand side', therefore, may have numbers that cannot be
+-- represented in a decQuad. Some testcases go to the limit of the
+-- next-wider format, and hence these testcases may also be used to
+-- test narrowing and widening operations.

+
+-- This set of tests is for the sixteen-byte concrete representation.
+-- Its characteristics are:
+--
+-- 1 bit sign
+-- 5 bits combination field
+-- 12 bits exponent continuation
+-- 110 bits coefficient continuation
+--
+-- Total exponent length 14 bits
+-- Total coefficient length 114 bits (34 digits)
+--
+-- Elimit = 12287 (maximum encoded exponent)
+-- Emax = 6144 (largest exponent value)
+-- Emin = -6143 (smallest exponent value)
+-- bias = 6176 (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.

+-- 1. Sanity checks and other three-operand tests (especially those
+-- where the fused operation makes a difference)
+-- 2. Multiply tests (third operand is neutral zero [0E+emax])
+-- 3. Addition tests (first operand is 1)
+-- The multiply and addition tests are extensive because FMA may have
+-- its own dedicated multiplication or addition routine(s), and they
+-- also inherently check the left-to-right properties.

+version: 2.56
+
+-- This set of tests tests the extended specification 'round-to-integral
+-- value-exact' operations (from IEEE 854, later modified in 754r).
+-- All non-zero results are defined as being those from either copy or
+-- quantize, so those are assumed to have been tested extensively
+-- elsewhere; the tests here are for integrity, rounding mode, etc.
+-- Also, it is assumed the test harness will use these tests for both
+-- ToIntegralExact (which does set Inexact) and the fixed-name
+-- functions (which do not set Inexact).
+
+-- Note that decNumber implements an earlier definition of toIntegral
+-- which never sets Inexact; the decTest operator for that is called
+-- 'tointegral' instead of 'tointegralx'.

+version: 2.56
+
+-- This file tests base conversions from string to a decimal number
+-- and back to a string (in Scientific form)
+
+-- Note that unlike other operations the operand is subject to rounding
+-- to conform to emax and precision settings (that is, numbers will
+-- conform to rules and exponent will be in permitted range). The
+-- 'left hand side', therefore, may have numbers that cannot be
+-- represented in a decSingle. Some testcases go to the limit of the
+-- next-wider format, and hence these testcases may also be used to
+-- test narrowing and widening operations.

+-- [Previously called decimal32.decTest]
+version: 2.56
+
+-- 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.

+-- 2. Multiply tests (third operand is neutral zero [0E+emax])

+-- The multiply and addition tests are extensive because FMA may have

+
+-- These testcases are taken from squareroot.decTest but are
+-- evaluated using the power operator. The differences in results
+-- (153 out of 2856) fall into the following categories:
+--
+-- x ** 0.5 (x>0) has no preferred exponent, and is Inexact
+-- (and hence full precision); almost all differences are
+-- in this category
+-- 0.00 ** 0.5 becomes 0 (not 0.0), etc.
+-- -0 ** 0.5 becomes 0 (never -0)
+-- Some exact subnormals become inexact and hence underflows

+-- (2) cases where the input exponent is outside the current context,
+-- and in particular when the result is subnormal
