| * ENH: avoid expensive clears in fenv functionsJulian Taylor2013-11-066-141/+183
| | | | | | | | | | | | | | | | | | | | Clearing is 50-100 times more expensive than checking on x86, so check if there is anything needs to be cleared first. This speeds up scalar operations by 10%-20%. Based on Arink Verma code in #3739. Implement the functions as new C-API functions npy_get_floatstatus and npy_clear_floatstatus in npy_math.

|\ \ | | | | | | BUG: hypot(inf, 0) shouldn't raise a warning
| * | BUG: fix handling of infs in hypot on windowsEric Moore2013-10-292-7/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On any platform where we used our own implementation of hypot, (e.g. windows) there were several issues with infs. hypot(inf, y) == inf, for all y including nan. We now check for inf and handle this case explicitly for all y instead of just y = nan. Although hypot(inf, 0) was correctly returning inf, it was incorrectly raising the invalid floating point exception. Fixes gh-2385

* | ENH: merge UFUNC_ERR_DEFAULT2 variable into UFUNC_ERR_DEFAULTJulian Taylor2013-10-224-6/+21
| | | | | | | | | | | | | | | | | | It seems it was added as a precaution to avoid breaking the rather complicated ufunc code. It effectively disabled the skipping of the dictionary lookup for the default values for the common case and leading to hardly tested code in third party libraries like pandas which set the error state to numpys old default (ignore all). The skipping improves scalar performance by 2.5-5%.
* | BUG: fix crash on default errobjJulian Taylor2013-10-221-3/+10

| * | BUG: core: ensure __r*__ has precedence over __numpy_ufunc__Pauli Virtanen2013-10-194-3/+294
| |/ | | | | | | | | | | | | | | | | | | | | | | | | Add a special case to the implementation of ndarray.__mul__ et al. that refuses to work on other objects that are not ndarray subclasses and implement both __numpy_ufunc__ and __r*__. This way, execution passes first to the custom __r*__ method, which makes it possible to have e.g. __mul__ and np.multiply do different things. Additionally, disable one __array_priority__ special case handling when also __numpy_ufunc__ is defined.

| | | | | | | | | | | | | | | | | | | | | | | | For every single operation calls, numpy has to extract value of buffersize, errormask and name to pack and build error object. These two functions, _extract_pyvals and PyUFunc_GetPyValues together use >12% of time.
