70c3289085 Replace occurrences of '\d' with '[0-9]' in Decimal regex, to make sure 
that the behaviour of Decimal doesn't change if/when re.UNICODE becomes
assumed in Python 3.0.

Also add a check that alternative Unicode digits (e.g. u'\N{FULLWIDTH
DIGIT ONE}') are *not* accepted in a numeric string.

72bc54faed Major change in the internal structure of the Decimal 
number: now it does not store the mantissa as a tuple
of numbers, but as a string.

This avoids a lot of conversions, and achieves a
speedup of 40%. The API remains intact.

Thanks Mark Dickinson.

9b5e23148b The constructor from tuple was way too permissive: it allowed bad 
coefficient numbers, floats in the sign, and other details that
generated directly the wrong number in the best case, or triggered
misfunctionality in the alorithms.

Test cases added for these issues. Thanks Mark Dickinson.

1a191df14d Made the various is_* operations return booleans. This was discussed 
with Cawlishaw by mail, and he basically confirmed that to these is_*
operations, there's no need to return Decimal(0) and Decimal(1) if
the language supports the False and True booleans.

Also added a few tests for the these functions in extra.decTest, since
they are mostly untested (apart from the doctests).

Thanks Mark Dickinson

6c398da0e7 The methods always return Decimal classes, even if they're 
executed through a subclass (thanks Mark Dickinson).
Added a bit of testing for this.

353750c405 Merged the decimal-branch (revisions 54886 to 58140). Decimal is now 
fully updated to the latests Decimal Specification (v1.66) and the
latests test cases (v2.56).

Thanks to Mark Dickinson for all his help during this process.

46cc702b72 test_main(): Restore the decimal context that was in 
effect at the time test_decimal was imported.  Else
running test_decimal had the bad side effect of
permanently changing the decimal context in effect.
That caused text_tokenize to fail if it ran after
test_decimal.

267b868f23 * Fix decimal's handling of foreign types. Now returns NotImplemented 
instead of raising a TypeError.  Allows other types to successfully
  implement __radd__() style methods.
* Remove future division import from test suite.
* Remove test suite's shadowing of __builtin__.dir().

ed20ad8473 Change the strategy for coping with time intensive tests from 
"all or none" to "all or some".

This provides much greater test coverage without eating much time.
It also makes it more likely that routine regression testing will
unearth bugs.

f63ba43733 * Dynamically build a list of files to be tested (necessary because 
version 2.39 of dectest.zip adds some new test files and because
  some existing test files were getting skipped).
* Remove two docstrings which cluttered unittest's output.
* Simplify a for-loop with a list comprehension.

b91af521fd * Hide a loop induction variable that was inadvertantly being picked up 
by the locals() call in the context constructor.

* Remove unnecessary properties for int, exp, and sign which duplicated
  information returned by as_tuple().
