* Issue 4796: Add from_float methods to the decimal module.Raymond Hettinger2009-01-031-56/+106
|
* Issue #4812: further renaming of internal Decimal constants, for clarity.Mark Dickinson2009-01-031-56/+56

* Issue #4812: add missing underscore prefix to some internal-use-onlyMark Dickinson2009-01-021-63/+63
| | | | constants in the decimal module. (Dec_0 becomes _Dec_0, etc.)
* Issue #4084: Fix max, min, max_mag and min_mag Decimal methods toFacundo Batista2008-12-111-16/+16
| | | | | | give correct results in the case where one argument is a quiet NaN and the other is a finite number that requires rounding. Thanks Mark Dickinson.
* Fix:Neal Norwitz2008-08-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | * crashes on memory allocation failure found with failmalloc * memory leaks found with valgrind * compiler warnings in opt mode which would lead to invalid memory reads * problem using wrong name in decimal module reported by pychecker Update the valgrind suppressions file with new leaks that are small/one-time leaks we don't care about (ie, they are too hard to fix). TBR=barry TESTED=./python -E -tt ./Lib/test/regrtest.py -uall (both debug and opt modes) in opt mode: valgrind -q --leak-check=yes --suppressions=Misc/valgrind-python.supp \ ./python -E -tt ./Lib/test/regrtest.py -uall,-bsddb,-compiler \ -x test_logging test_ssl test_multiprocessing valgrind -q --leak-check=yes --suppressions=Misc/valgrind-python.supp \ ./python -E -tt ./Lib/test/regrtest.py test_multiprocessing for i in `seq 1 4000` ; do LD_PRELOAD=~/local/lib/libfailmalloc.so FAILMALLOC_INTERVAL=$i \ ./python -c pass done At least some of these fixes should probably be backported to 2.5.
* Issue 2235: __hash__ is once again inherited by default, but inheritance can ↵Nick Coghlan2008-07-151-4/+2

* Replace occurrences of '\d' with '[0-9]' in Decimal regex, to make sureMark Dickinson2008-07-021-10/+10
| | | | | | | | 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.
* Make sure that Context traps and flags dictionaries have values 0 and 1Mark Dickinson2008-05-041-2/+2
| | | | (as documented) rather than True and False.
* Some very minor changes to decimal.py in Python 2.6, aimedMark Dickinson2008-05-041-9/+9
| | | | | | | | | | at reducing the size of the diff between the 2.x decimal.py and 3.x decimal.py and thereby making future merges easier: - replace one instnace of an old-style raise statement - define __div__ in terms of __truediv__ instead of the other way around - make wording match on an exception message
* Backport Raymond's changes in r60508 to Python 2.6.Mark Dickinson2008-05-031-4/+4

* Fixed some test structures. Thanks Mark Dickinson.Facundo Batista2008-05-021-5/+1

* Issue #2482: Make sure that the coefficient of a DecimalMark Dickinson2008-03-251-3/+3
| | | | | instance is always stored as a str instance, even when that Decimal has been created from a unicode string.
* Issue #2478: Decimal(sqrt(0)) failed when the decimal contextMark Dickinson2008-03-251-3/+3
| | | | was not explicitly supplied.
* Fix docstring typo.Mark Dickinson2008-02-291-1/+1

* Bring decimal a bit closer to the spec for Reals.Raymond Hettinger2008-02-121-0/+14

* Issue 1979: Make Decimal comparisons (other than !=, ==) involving NaNMark Dickinson2008-02-061-39/+110

* Add support for trunc().Raymond Hettinger2008-01-241-0/+2

* Issue 1780: Allow leading and trailing whitespace in Decimal constructor,Mark Dickinson2008-01-121-3/+14
| | | | | when constructing from a string. Disallow trailing newlines in Context.create_decimal.
* Have Decimal.as_tuple return a named tuple.Raymond Hettinger2008-01-111-1/+7

* Issue #1757: The hash of a Decimal instance is no longer affectedFacundo Batista2008-01-081-3/+11

* Some minor cleanups. Thanks Mark Dickinson.Facundo Batista2007-12-191-34/+19
|
* Removed the private _rounding_decision: it was not needed, and the codeFacundo Batista2007-12-171-94/+38
| | | | is now simpler. Thanks Mark Dickinson.
* fma speedup by avoiding to create a Context. Thanks Mark Dickinson.Facundo Batista2007-12-041-16/+31
|
* Faster _fix function, and some reordering for a more elegantFacundo Batista2007-12-031-52/+47

* Speedup and cleaning of __str__. Thanks Mark Dickinson.Facundo Batista2007-12-031-71/+41

* Reordering of __new__ to minimize isinstance() calls to mostFacundo Batista2007-11-301-55/+56

* Major change in the internal structure of the DecimalFacundo Batista2007-11-231-302/+219
| | | | | | | | | | 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.
* The constructor from tuple was way too permissive: it allowed badFacundo Batista2007-10-191-10/+36
| | | | | | | | 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.
* Added a class to store the digits of log(10), so that they can be madeFacundo Batista2007-10-021-16/+49
| | | | available when necessary without recomputing. Thanks Mark Dickinson
* Made the various is_* operations return booleans. This was discussedFacundo Batista2007-10-021-112/+95
| | | | | | | | | | | 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
* Issue #1772851. Optimization of __hash__ to behave better for big bigFacundo Batista2007-09-191-4/+11

* Speed up of the various division operations (remainder, divide,Facundo Batista2007-09-181-161/+139
| | | | divideint and divmod). Thanks Mark Dickinson.
* The methods always return Decimal classes, even if they'reFacundo Batista2007-09-171-34/+38
| | | | | executed through a subclass (thanks Mark Dickinson). Added a bit of testing for this.
* Put the parameter watchexp back in (changed watchexp from an intFacundo Batista2007-09-131-2/+13
| | | | | | | to a bool). Also second argument to watchexp is now converted to Decimal, just as with all the other two-argument operations. Thanks Mark Dickinson.
* Merged the decimal-branch (revisions 54886 to 58140). Decimal is nowFacundo Batista2007-09-131-702/+2846
| | | | | | | 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.
* When passed a bad formed literal to Decimal, now we have aFacundo Batista2007-08-151-1/+2

* Whitespace normalization. Ugh, we really need to do this more often.Neal Norwitz2007-04-251-4/+4
| | | | You might want to review this change as it's my first time. Be gentle. :-)
* General clean-up. Lot of margin corrections, comments, some typos.Facundo Batista2007-04-101-159/+170
| | | | | Exceptions now are raised in the new style. And a mockup class is now also new style. Thanks Santiago Pereson.
