808180c206 Fast path for int inputs to math.dist() and math.hypot() (GH-11692) 2019-01-28 13:59:56 -08:00

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.

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.

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.

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.

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.

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.

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.

c630e10440 Factor-out common code. Also, optimize common cases by preallocating space on the stack. GH-8738 
Improves speed by 9 to 10ns per call.

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.

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.

tgamma(), lgamma(), erf() and erfc().

* Don't use tgamma() and lgamma() from libc on OS X.
