|\ \ | | | | | | ENH: improve duck typing inside iscomplexobj
| * | ENH: improve duck typing inside iscomplexobjMichael Goerz2016-08-151-0/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Both `iscomplexobj` and `isrealobj` now try to refer to the argument's `dtype` attribute if it exists. This significantly extends the list of types for which `iscomplexobj` returns correct results (including e.g. scipy sparse matrices and pandas objects). Extended the tests of the `iscomplexobj` routine for the following cases: * simple scalars * standard lists (test internal auto-conversion to numpy arrays) * "Duck typing" for objects that define a dtype attribute (either referring to one of the existing numpy dtypes, or a custom dtype, as pandas does) This fixes #7924

But the Patlib version on PyPi that can be installed for Python 2.7 doesn't accept strings, gives errors like: ====================================================================== ERROR: test_ndfromtxt (test_io.TestPathUsage) ---------------------------------------------------------------------- Traceback (most recent call last): File "/home/rgommers/Code/numpy/numpy/testing/decorators.py", line 147, in skipper_func return f(*args, **kwargs) File "/home/rgommers/Code/numpy/numpy/lib/tests/test_io.py", line 1888, in test_ndfromtxt f.write('1 2\n3 4') TypeError: must be unicode, not str

Closes gh-6974. Addendum: this commit also appears to have fixed issue with overflow for very large input arrays. Closes gh-7207.

|/ / / | | | | | | | | | | | | | | | | | | | | | | | | nanpercentile was conforming to dimension convention of percentile incorrectly. percentile outputs results for the different percentiles along the first dimension of the output. nanpercentile was moving the reduction axis to the front using swapaxes, which would move the first axis out of place if there were more than two in the array. Added a test with more than two axes to demonstrate and used rollaxis instead of swapaxes to do the interhange.
