* Issue #15882: Change _decimal to accept any coefficient tuple whenStefan Krah2012-09-101-0/+7
| | | | | | constructing infinities. This is done for backwards compatibility with decimal.py: Infinity coefficients are undefined in _decimal (in accordance with the specification).
* Issue #15544: Fix Decimal.__float__ to work with payload-carrying NaNs.Mark Dickinson2012-08-241-1/+17

* mpd_qpowmod(): calculate result with zero-exponent for compatibility withStefan Krah2012-08-232-23/+17

* Use zero bottom margin.Stefan Krah2012-08-221-3/+0

* In the 32-bit build, dec_hash() raised InvalidOperation if the operandStefan Krah2012-08-222-4/+57
| | | | | | 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!).
* 1) Use _mpd_basedivmod() regardless of the length of the dividend. This isStefan Krah2012-08-221-6/+9
| | | | | | | | | | 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.
* Add unused parameter to a couple of METH_NOARGS functions. The previousStefan Krah2012-07-281-8/+8
| | | | | form is used in many places in the source tree, but was found to be incorrect in a recent tracker discussion.

* Issue #7652: Clean up _mpd_qinvroot() and mark it LIBMPDEC_ONLY. Use theStefan Krah2012-07-121-135/+140

* After 79d2eb29c755 it is no longer necessary to zero the output array:Stefan Krah2012-06-301-4/+4
| | | | | | 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.
* Proactive reliability fix for broken FPUs: The base conversion functionsStefan Krah2012-06-305-198/+409
| | | | | | | | | | 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.
* Update test script to Visual Studio 2010.Stefan Krah2012-06-252-42/+32

* Make the benchmark more fair for _decimal/decimal.py by setting context.precStefan Krah2012-06-241-6/+6
| | | | only once (float obviously doesn't set any context at all).
* Speed up _decimal by another 10-15% by caching the thread local contextStefan Krah2012-06-241-21/+58
| | | | | that was last accessed. In the pi benchmark (64-bit platform, prec=9), _decimal is now only 1.5x slower than float.

* Fix comment.Stefan Krah2012-06-201-1/+1
|
* Many cleanups of redundant code in mpd_qrem_near():Stefan Krah2012-06-201-23/+15
| | | | | | | | | | | | | | | | | | 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).
* Add comments to the power functions, in particular to _mpd_qpow_real().Stefan Krah2012-06-181-5/+34
|
* 1) State the relative errors of the power functions for integer exponents.Stefan Krah2012-06-161-2/+18
| | | | | | | | | | | | | | | 2) _mpd_qpow_mpd(): Abort the loop for all specials, not only infinity. 3) _mpd_qpow_mpd(): Make the function more general and distinguish between zero clamping and folding down the exponent. The latter case is currently handled by setting context->clamp to 0 before calling the function. 4) _mpd_qpow_int(): Add one to the work precision in case of a negative exponent. This is to get the same relative error (0.1 * 10**-prec) for both positive and negative exponents. The previous relative error for negative exponents was (0.2 * 10**-prec). Both errors are _before_ the final rounding to the context precision.
* 1) Fix signature of _mpd_qpow_uint(): contrary to the comment base is constant.Stefan Krah2012-06-121-7/+9
| | | | | | | | 2) Abort the loop for all specials, not only infinity. 3) Make the function more general and distinguish between zero clamping and folding down the exponent. The latter case is currently handled by setting context->clamp to 0 before calling the function.
* 1) Replace long-winded abort() construct by assert().Stefan Krah2012-06-111-31/+28
| | | | | 2) Remove micro optimization (inline checking for NaN before calling mpd_qcheck_nans()) that probably has no benefit in this case.
