Pablo Galindo	0411411c6b	Rework integer overflow path in math.prod and add more tests (GH-11809) The overflow check was relying on undefined behaviour as it was using the result of the multiplication to do the check, and once the overflow has already happened, any operation on the result is undefined behaviour. Some extra checks that exercise code paths related to this are also added.	7 years ago
Dima Pasechnik	f57cd8288d	bpo-36106: Resolve sinpi name clash with libm (IEEE-754 violation). (GH-12027) The standard math library (libm) may follow IEEE-754 recommendation to include an implementation of sinPi(), i.e. sinPi(x):=sin(pi*x). And this triggers a name clash, found by FreeBSD developer Steve Kargl, who worken on putting sinpi into libm used on FreeBSD (it has to be named "sinpi", not "sinPi", cf. e.g. https://en.cppreference.com/w/c/experimental/fpext4).	7 years ago
Pablo Galindo	4207907c2b	Fix division by 0 when checking for overflow in math.prod (GH-11808)	7 years ago
Pablo Galindo	bc09851586	bpo-35606: Implement math.prod (GH-11359)	7 years ago
Raymond Hettinger	cfd735ea28	Move float conversion into a macro. Apply to fsum (GH-11698)	7 years ago
Raymond Hettinger	808180c206	Fast path for int inputs to math.dist() and math.hypot() (GH-11692)	7 years ago
Serhiy Storchaka	d0d3e99120	bpo-35719: Optimize multi-argument math functions. (GH-11527) Use the fast call convention for math functions atan2(), copysign(), hypot() and remainder() and inline unpacking arguments. This sped up them by 1.3--2.5 times.	7 years ago
Ammar Askar	cb08a71c5c	bpo-34838: Use subclass_of for math.dist. (GH-9659) Argument clinic now generates fast inline code for positional parsing, so the manually implemented type check in math.dist can be removed.	7 years ago
Zackery Spytz	4c49da0cb7	bpo-35436: Add missing PyErr_NoMemory() calls and other minor bug fixes. (GH-11015) Set MemoryError when appropriate, add missing failure checks, and fix some potential leaks.	7 years ago
Raymond Hettinger	216aaaa056	Fixing wording in comment. (GH-10425) Since the n==1 case just returns max, it cannot be larger than the magnitude of the vector entry.	7 years ago
Raymond Hettinger	df8101517a	Speed-up math.dist() by 30% (GH-9628)	7 years ago
Pablo Galindo	e9ba3705de	bpo-33083 - Make math.factorial reject arguments that are not int-like (GH-6149) math.factorial() was accepting non-integral Decimal instances. This is inconsistent with the actual behaviour for floats, which are not accepted.	8 years ago
Raymond Hettinger	f326714426	Minor improvement to code clarity (GH-9036) Make it clear that the n==0 case is included. Otherwise, you have to know that max==0.0 whenever n==0.	8 years ago
Raymond Hettinger	745c0f3980	Simplify vector_norm() by eliminating special cases in the main loop (GH-9006) The max value is no longer treated as a special case in the main loop. Besides making the main loop simpler and branchless, this also lets us relax the input restriction of vec to contain only non-negative values.	8 years ago

Barry Warsaw	b2e5794870	bpo-31338 (#3374 ) * Add Py_UNREACHABLE() as an alias to abort(). * Use Py_UNREACHABLE() instead of assert(0) * Convert more unreachable code to use Py_UNREACHABLE() * Document Py_UNREACHABLE() and a few other macros.	9 years ago
Mark Dickinson	a0ce375e10	bpo-29962: add math.remainder (#950 ) * Implement math.remainder. * Fix markup for arguments; use double spaces after period. * Mark up function reference in what's new entry. * Add comment explaining the calculation in the final branch. * Fix out-of-order entry in whatsnew. * Add comment explaining why it's good enough to compare m with c, in spite of possible rounding error.	9 years ago

Serhiy Storchaka	97553fdf9d	bpo-26121: Use C library implementation for math functions: (#515 ) * bpo-26121: Use C library implementation for math functions: tgamma(), lgamma(), erf() and erfc(). * Don't use tgamma() and lgamma() from libc on OS X.	9 years ago

Victor Stinner	f17c3de263	Use _PyObject_CallNoArg() Replace: PyObject_CallFunctionObjArgs(callable, NULL) with: _PyObject_CallNoArg(callable)	9 years ago
Victor Stinner	de4ae3d486	Backed out changeset b9c9691c72c5 Issue #28858: The change b9c9691c72c5 introduced a regression. It seems like _PyObject_CallArg1() uses more stack memory than PyObject_CallFunctionObjArgs().	9 years ago
Victor Stinner	27580c1fb5	Replace PyObject_CallFunctionObjArgs() with fastcall * PyObject_CallFunctionObjArgs(func, NULL) => _PyObject_CallNoArg(func) * PyObject_CallFunctionObjArgs(func, arg, NULL) => _PyObject_CallArg1(func, arg) PyObject_CallFunctionObjArgs() allocates 40 bytes on the C stack and requires extra work to "parse" C arguments to build a C array of PyObject*. _PyObject_CallNoArg() and _PyObject_CallArg1() are simpler and don't allocate memory on the C stack. This change is part of the fastcall project. The change on listsort() is related to the issue #23507.	9 years ago
