 2015-12-28 23:02:02 +01:00
Serhiy Storchaka 5c4064e8bd Issue #25421: __sizeof__ methods of builtin types now use dynamic basic size. 
This allows sys.getsize() to work correctly with their subclasses with
__slots__ defined.
 2015-12-19 20:05:25 +02:00
Serhiy Storchaka 20b39b27d9 Removed redundant casts to `char *`. 
Corresponding functions now accept `const char *` (issue #1772673).

Stefan Krah cf26115651 Introduce and check for MPD_VERSION_HEX for precise management of builds 
with an external libmpdec.

Stefan Krah 8fb74a35da Issue #21374: Fix pickling of DecimalTuple. 2014-04-29 18:24:50 +02:00
Benjamin Peterson ce68c19ee7 remove unused zero constants 2014-03-15 11:49:49 -05:00
Stefan Krah 45059eb1d0 1) Prepare libmpdec for the 2.4.0 release. None of the following changes affects 
_decimal:

      o Make all "mpd_t to C integer" conversion functions available in both the
        64-bit and the 32-bit versions.

      o Make all mixed mpd_t/C integer arithmetic functions available in the
        32-bit version.

      o Better handling of __STDC_LIMIT_MACROS for C++ users.

      o Add struct tags (at the request of C++ users).

2) Check for libmpdec.so.2 if --with-system-libmpdec is used.

Stefan Krah 2fdf4e7b9b Move PyErr_NoMemory() closer to the failure. 2013-11-08 18:05:02 +01:00
Stefan Krah a0fd1f5a18 Change style to match the surrounding code (no early returns). 2013-11-08 17:48:58 +01:00
Victor Stinner ac470854b8 Issue #19437: Fix dec_format() of the _decimal module, handle dec_strdup() 
failure (memory allocation failure): raise a MemoryError exception
 2013-10-29 20:33:14 +01:00
Victor Stinner a992e11fe3 Issue #19437: Fix convert_op_cmp() of decimal.Decimal rich comparator, handle 
PyObject_IsInstance() failure
 2013-10-29 19:26:11 +01:00
Stefan Krah 891ca9e06a Backport bff16086f03b and bcaaaa00425b. 2013-05-29 19:14:17 +02:00
Stefan Krah 6edda14b29 Issue #17768: Support newline fill character in decimal.py and NUL fill 
character in _decimal.c.
 2013-05-29 15:45:38 +02:00
Stefan Krah eb8c451bd2 Since the return type of format() is not a Decimal, raise ValueError instead of 
InvalidOperation if the format specification (width, prec) exceeds the internal
limits of libmpdec.
 2013-01-24 15:22:33 +01:00
Stefan Krah 59a4a93f43 Issue #16422: Use strings for rounding mode constants for better readability 
and pickling compatibility.
 2013-01-16 12:58:59 +01:00
Stefan Krah fb7f580e81 Issue #16745: Hide a couple of symbols by making them local. 2012-12-21 23:11:05 +01:00
Stefan Krah 9a4ff437d1 Issue #15783: Support None default values in the Context() constructor. 2012-12-16 21:10:35 +01:00
Stefan Krah 040e311826 Issue #15783: Except for the number methods, the C version of decimal now 
supports all None default values present in decimal.py. These values were
largely undocumented.
 2012-12-15 22:33:33 +01:00
Stefan Krah 6e467049c6 Accept Unicode legacy strings in the Decimal constructor. 2012-11-10 23:09:04 +01:00
Stefan Krah 0f82b76b57 Issue #16431: Finally, consider all permutations. 2012-11-08 11:17:29 +01:00
Stefan Krah ed16eff57e Issue #16431: Also fix the opposite direction. 2012-11-07 23:47:19 +01:00
Stefan Krah f4abc7b8a0 Issue #16431: Use the type information when constructing a Decimal subtype 
from a Decimal argument.
 2012-11-07 23:12:25 +01:00
Stefan Krah dbcf103be0 Issue #15882: Change _decimal to accept any coefficient tuple when 
constructing infinities. This is done for backwards compatibility
with decimal.py: Infinity coefficients are undefined in _decimal
(in accordance with the specification).
 2012-09-10 19:34:58 +02:00
Mark Dickinson fc33d4ce0a Issue #15544: Fix Decimal.__float__ to work with payload-carrying NaNs. 2012-08-24 18:53:10 +01:00
Stefan Krah f21587e3a8 mpd_qpowmod(): calculate result with zero-exponent for compatibility with 
decimal.py. The hack to remove the ideal exponent is no longer required.
 2012-08-23 15:05:29 +02:00
Stefan Krah ad5b43995e In the 32-bit build, dec_hash() raised InvalidOperation if the operand 
had a coefficient with MAX_PREC=425000000 digits and a negative exponent.
Increasing the context limits above the official values fixes the issue
and is safe (in this case!).
 2012-08-22 19:11:50 +02:00
Stefan Krah b9e36b97f2 Add unused parameter to a couple of METH_NOARGS functions. The previous 
form is used in many places in the source tree, but was found to be incorrect
in a recent tracker discussion.
 2012-07-28 13:53:47 +02:00
Stefan Krah c35a8e5c98 Proactive reliability fix for broken FPUs: The base conversion functions 
use log10() to calculate the size of the output array. The current code
has been tested on x86/amd64 (and to a lesser extent on qemu-mips qemu-sparc)
and produces sufficiently large values for all inputs tested so far (coefficient
sizes of 10**18 - 1 are hard to test exhaustively).

The new code does not rely on the correctness of log10() and resizes
the output arrays if the allocated space is insufficient.
 2012-06-30 18:05:33 +02:00
Stefan Krah 78f075636c Speed up _decimal by another 10-15% by caching the thread local context 
that was last accessed. In the pi benchmark (64-bit platform, prec=9),
_decimal is now only 1.5x slower than float.
 2012-06-24 12:20:03 +02:00
Stefan Krah cc74b6ab14 Issue #14478: Cache the hash of a Decimal in the C version. 2012-04-10 16:27:58 +02:00
Stefan Krah e37f8b29fc Issue #14520: Add __sizeof__() method to the Decimal object. 2012-04-09 21:27:20 +02:00
Stefan Krah dd159ce606 Speed up _decimal by 30-40% for numerical workloads by improving the cache 
locality for regularly sized coefficients.
 2012-04-09 20:24:57 +02:00
Stefan Krah 94ef3e4c1d Use the MPD() accessor macro. 2012-04-09 19:20:46 +02:00
Stefan Krah 4771cca817 Whitespace. 2012-04-05 16:15:25 +02:00
Stefan Krah 871b96bd5a Reduce array size. 2012-04-05 16:07:22 +02:00
Stefan Krah a6169484c2 Formatting. 2012-04-05 15:48:59 +02:00
Stefan Krah ff3eca0cc3 Allow printing a leading '-' and the maximum number of exponent digits 
rather than raising RuntimeError (allocated space is sufficient for the
additional character).
 2012-04-05 15:46:19 +02:00
Stefan Krah 0774e9b9f5 Raise InvalidOperation if exponents of zeros are clamped during exact 
conversion in the Decimal constructor. Exact here refers to the
representation and not to the value (clamping does not change the value).
 2012-04-05 15:21:58 +02:00
Stefan Krah 91c0274bc4 Improve comments. 2012-04-02 20:51:08 +02:00
Stefan Krah 5100171d81 Clear the context flags if a context is initialized from the DefaultContext. 2012-04-02 15:02:21 +02:00
Stefan Krah fe17b2bc77 Raise MemoryError instead of InvalidOperation/MallocError for compatibility 
with decimal.py. The standard specifies InsufficientStorage (MallocError) as
a sub-condition of InvalidOperation. This allows a calculation to continue
with NaN results when allocation fails.
 2012-03-25 18:59:21 +02:00
Stefan Krah b6405efd1b Use the same exception hierarchy as decimal.py. FloatOperation now also 
inherits from TypeError. Cleanup in module initialization to make repeated
import failures robust.
 2012-03-23 14:46:48 +01:00
Stefan Krah 7cc5521d40 Whitespace. 2012-03-21 20:21:20 +01:00
Stefan Krah 1919b7e72b Issue #7652: Integrate the decimal floating point libmpdec library to speed 
up the decimal module. Performance gains of the new C implementation are
between 12x and 80x, depending on the application.
