Guido van Rossum	4668b000a1	Implement PEP 238 in its (almost) full glory. This introduces: - A new operator // that means floor division (the kind of division where 1/2 is 0). - The "future division" statement ("from __future__ import division) which changes the meaning of the / operator to implement "true division" (where 1/2 is 0.5). - New overloadable operators __truediv__ and __floordiv__. - New slots in the PyNumberMethods struct for true and floor division, new abstract APIs for them, new opcodes, and so on. I emphasize that without the future division statement, the semantics of / will remain unchanged until Python 3.0. Not yet implemented are warnings (default off) when / is used with int or long arguments. This has been on display since 7/31 as SF patch #443474. Flames to /dev/null.	25 years ago

Tim Peters	0f33604e17	SF bug [ #409448 ] Complex division is braindead http://sourceforge.net/tracker/?func=detail&aid=409448&group_id=5470&atid=105470 Now less braindead. Also added test_complex.py, which doesn't test much, but fails without this patch.	26 years ago
Tim Peters	7069512bd0	When 1.6 boosted the # of digits produced by repr(float), repr(complex) apparently forgot to play along. Make complex act like float.	26 years ago
Guido van Rossum	be4cbb1668	Use rich comparisons to fulfill an old wish: complex numbers now raise exceptions when compared using <, <=, > or >=. NOTE: This is a tentative change: this means that cmp() involving complex numbers will raise an exception when the numbers differ, and that in turn means that e.g. dictionaries and certain other compounds (e.g. UserLists) containing complex numbers can't be compared either. So we'll have to decide whether this is acceptable. The alpha test cycle is a good time to keep an eye on this!	26 years ago
Fred Drake	d5fadf75e4	Rationalize use of limits.h, moving the inclusion to Python.h. Add definitions of INT_MAX and LONG_MAX to pyport.h. Remove includes of limits.h and conditional definitions of INT_MAX and LONG_MAX elsewhere. This closes SourceForge patch #101659 and bug #115323.	26 years ago
Guido van Rossum	8586991099	REMOVED all CWI, CNRI and BeOpen copyright markings. This should match the situation in the 1.6b1 tree.	26 years ago
Tim Peters	39dce29365	Fix for http://sourceforge.net/bugs/?func=detailbug&bug_id=111866&group_id=5470 . This was a misleading bug -- the true "bug" was that hash(x) gave an error return when x is an infinity. Fixed that. Added new Py_IS_INFINITY macro to pyport.h. Rearranged code to reduce growing duplication in hashing of float and complex numbers, pushing Trent's earlier stab at that to a logical conclusion. Fixed exceedingly rare bug where hashing of floats could return -1 even if there wasn't an error (didn't waste time trying to construct a test case, it was simply obvious from the code that it could happen). Improved complex hash so that hash(complex(x, y)) doesn't systematically equal hash(complex(y, x)) anymore.	26 years ago

Fred Drake	13634cf7a4	This patch addresses two main issues: (1) There exist some non-fatal errors in some of the hash algorithms. For exmaple, in float_hash and complex_hash a certain part of the value is not included in the hash calculation. See Tim's, Guido's, and my discussion of this on python-dev in May under the title "fix float_hash and complex_hash for 64-bit nix" (2) The hash algorithms that use pointers (e.g. func_hash, code_hash) are universally not correct on Win64 (they assume that sizeof(long) == sizeof(void)) As well, this patch significantly cleans up the hash code. It adds the two function _Py_HashDouble and _PyHash_VoidPtr that the various hashing routine are changed to use. These help maintain the hash function invariant: (a==b) => (hash(a)==hash(b))) I have added Lib/test/test_hash.py and Lib/test/output/test_hash to test this for some cases.	26 years ago
Guido van Rossum	b18618dab7	Vladimir Marangozov's long-awaited malloc restructuring. For more comments, read the patches@python.org archives. For documentation read the comments in mymalloc.h and objimpl.h. (This is not exactly what Vladimir posted to the patches list; I've made a few changes, and Vladimir sent me a fix in private email for a problem that only occurs in debug mode. I'm also holding back on his change to main.c, which seems unnecessary to me.)	26 years ago
Guido van Rossum	43713e5a28	Massive patch by Skip Montanaro to add ":name" to as many PyArg_ParseTuple() format string arguments as possible.	27 years ago
Guido van Rossum	bffd683f73	The rest of the changes by Trent Mick and Dale Nagata for warning-free compilation on NT Alpha. Mostly added casts etc.	27 years ago
Guido van Rossum	3bbef60990	Ai! complex_nonzero() has && which should be \|\|, else decidedly non-zero things like 5j and complex(1,0) are considered to be zero/false. Tim Peters.	28 years ago

Guido van Rossum	967839473a	Got rid of c_error in favor of errno (and EDOM/ERANGE). Assume that errno usage is thread-safe -- most vendors do this by making in a macro that refers to a per-thread storage area.	29 years ago
