Decimal module and test cases were updated to their state of
the art. It now complies latest specification and tests.
The only difference of this version with the one in the trunk
is that a small subset that hash tests were removed, because
they rely on modifications to core hash() function (see
issue 1182 for further details).

+ # these tests are passed do we go on to actually compute x**y.
+
+ # Here's the main idea. First normalize both x and y. We

+ # *any* precision), xc must be the nth power of a positive

+ # then:
+ #
+ # (1) if xc != 1 then for the result to be representable we
+ # need xc**(1/n) >= 2, and hence also xc**|y| >= 2. So
+ # if |y| <= 1/nbits(xc) then xc < 2**nbits(xc) <=
+ # 2**(1/|y|), hence xc**|y| < 2 and the result is not
+ # representable.

+ # (2) if xe != 0, |xe|*(1/n) >= 1, so |xe|*|y| >= 1. Hence if
+ # |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,
+ # so if it's representable then xc**y < 10**p, and y <

+-- 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.

+-- for this operation 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.

+
+-- 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.

+-- Similarly, comparetotal will have some radically different paths

+-- overflow or underflow, so actual subtractions are not necessary).
+-- Similarly, comparetotal will have some radically different paths
+-- than compare.

+-- 8 bits exponent continuation
+-- 50 bits coefficient continuation

+-- Total exponent length 10 bits
+-- Total coefficient length 54 bits (16 digits)

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

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

+version: 2.57
+
+-- 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: 2.57
+
+-- 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.

+-- overflow or underflow, so actual subtractions are not necessary).
+-- Similarly, comparetotal will have some radically different paths
+-- than compare.
+
+-- All operands and results are decQuads.

+-- 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'

+-- 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: 2.57
+
+-- 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'.

+
+-- 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.

+-- 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
