* BUG: fix native-only long long checkJulian Taylor2014-01-041-2/+2
| | | | | | Caused all long longs to be required native only in memoryviews. NPY_SIZEOF_LONG_LONG never existed, replace documentation with existing NPY_SIZEOF_LONGLONG and code with a sizeof(npy_longlong).

* ENH: avoid expensive clears in fenv functionsJulian Taylor2013-11-062-0/+43
| | | | | | | | | | 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: core: ensure __r*__ has precedence over __numpy_ufunc__Pauli Virtanen2013-10-191-0/+29
| | | | | | | | | | | | | 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.

* MAINT: Refactor nanfunctions.Charles Harris2013-08-121-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | nanmax, nanmin -------------- Add out and keepdims keywords. nanargmin, nanargmax -------------------- A NanWarning is raised if an all NaN slice detected. For all such slices np.iingo(np.intp).min is returned as the index value. nansum ------ The keywords dtype, out, and keepdims are added. A FutureWarning is raised, as in the future the mean of an empty slice after NaN replacement will be 0 instead of the current NaN. nanmean, nanvar, nanstd ----------------------- For all, if the input array is of inexact type then the dtype and out parameters must be of inexact type if specified. That insures that NaNs can be returned when appropriate. The nanmean function detects empty slices after NaN replacement and raises a NanWarning. NaN is returned as the value for all such slices. The nanmean and nanstd functions detect degrees of freedom <= 0 after NaN replacement and raise a NanWarning. NaN is returned as the value for all such slices.
* ENH: add quickselect algorithm and expose it via partitionJulian Taylor2013-08-122-9/+32
| | | | | | | | | | | | | | | | | | | | | | | | A partition sorts the kth element into its sorted order and moves all smaller elements before the kth element and all equal or greater elements behind it. The ordering of all elements in the partitions is undefined. It is implemented via the introselection algorithm which has worst case linear complexity compared to a full sort that has linearithmic complexity. The introselect algorithm uses a quickselect with median of three pivot and falls back to a quickselect with median of median of five pivot if no sufficient progress is made. The pivots used during the search for the wanted kth element can optionally be stored and reused for further partitionings of the array. This is used by the python interface if an array of kth is provided to the partitions function. This improves the performance of median and which need to select two elements if the size of the array is even. A percentile function interpolating between values also profits from this. String selection is implemented in terms of quicksort which has the same properties as a selection for now.

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | In python3 range is an iterator and `xrange` has been removed. This has two consequence for code: 1) Where a list is needed `list(range(...))` must be used. 2) `xrange` must be replaced by `range` Both of these changes also work in python2 and this patch makes both. There are three places fixed that do not need it, but I left them in so that the result would be `xrange` clean. Closes #3092

* FIX: Transition scheme for safer in-place ufunc operationsNathaniel J. Smith2012-09-201-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | In numpy 1.6 and earlier, if you do np.add(int_arr, float_arr, out=int_arr) or int_arr += float_arr then the result will be silently truncated to integer values. This often produces bugs, because it's easy to accidentally end up with an integer array and not realize it. Therefore, there seems to be consensus that we should switch to using same_kind casting by default for in-place ufunc operations. However, just switching this (as was done initially during the 1.7 development cycle) breaks a lot of code, which is rude and violates our deprecation policy. This commit instead adds a special temporary casting rule which acts like "unsafe", but also checks whether each operation would be allowed under "same_kind" rules and issues a DeprecationWarning if not. It also moves NPY_DEFAULT_ASSIGN_CASTING into the formal API instead of leaving it as a #define. This way we can change it later, and any code which references it and is compiled against this version of numpy will automatically switch to whatever we change it too. This avoids the situation where we want to remove the temporary magic value we're using to create DeprecationWarnings now, but can't because it would be an ABI break.
