Ezio Melotti 3f5db3940f Fix a few typos and a double semicolon. Patch by Eitan Adler. 2013-01-27 06:20:14 +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.

largely undocumented.

Stefan Krah 7e6523fbd7 Use C-style comments. 2012-09-23 15:46:09 +02:00
Stefan Krah 76e12179c5 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 17183a2972 Use zero bottom margin. 2012-08-22 19:28:12 +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 2fd502f6a1 1) Use _mpd_basedivmod() regardless of the length of the dividend. This is 
required for a corner case in dec_hash() in the following commit and also
   usually faster. dec_hash() needs some extra precision above MPD_MAX_PREC,
   and _mpd_base_ndivmod() is not audited for that.

2) Use _mpd_basemul() if the length of the smaller operand is less than
   or equal to 256. While this is technically an optimization, it is
   required for *testing* corner cases in dec_hash() in reasonable time.
 2012-08-22 18:54:37 +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 26a1c7a905 Fix Visual Studio warning. 2012-07-20 12:34:18 +02:00
Stefan Krah e574402bd6 Issue #7652: Clean up _mpd_qinvroot() and mark it LIBMPDEC_ONLY. Use the 
algorithm from decimal.py for mpd_qsqrt().
 2012-07-12 21:17:59 +02:00
Stefan Krah d57caf36bd Remove ISSUES.txt. 2012-07-01 12:24:20 +02:00
Stefan Krah 5431e30853 After 79d2eb29c755 it is no longer necessary to zero the output array: 
None of the _mpd_shortadd() or _mpd_shortmul() functions read uninitialized
values. Previously zeroing was required since _mpd_real_size() was called
on the output array.
 2012-06-30 21:57:49 +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 1edab78859 Update test script to Visual Studio 2010. 2012-06-25 14:41:37 +02:00
Stefan Krah 39e810eb6c Make the benchmark more fair for _decimal/decimal.py by setting context.prec 
only once (float obviously doesn't set any context at all).
 2012-06-24 14:10:49 +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.

Stefan Krah 3077ab8237 Whitespace. 2012-06-23 00:31:04 +02:00
Stefan Krah 50b0a365ba Fix comment. 2012-06-20 23:38:51 +02:00
Stefan Krah 22385011ed Many cleanups of redundant code in mpd_qrem_near(): 
1) _mpd_qdivmod() uses the context precision only in two places, and
     the new code should be exactly equivalent to the previous code.

  2) Remove misleading comment.

  3) The quotient *is* an integer with exponent 0, so calling mpd_qtrunc()
     is pointless.

  4) Replace two instances of identical code by a single one.

  5) Use _mpd_cmp_abs() instead of mpd_cmp_total_mag(): the operands
     are not special.

  6) Don't clear MPD_Rounded in the status (with the current code it should
     not be set within the function).
