| * DOC: Hint at lib.format.open_memmap from np.load and np.memmapJan Schlüter2016-08-291-0/+1
| | | | | | | | | | | | | | np.load supports memmap_mode to open existing .npy files as memory-mapped files. np.memmap supports creating or loading raw binary files as memory-mapped files. This adds a link to a function for creating memory-mapped files in .npy format.

* BUG: fix #4381: precision loss on string -> longdouble conversionAnne Archibald2015-08-281-0/+2
| | | | | | | | | | | | | | | Avoid going through python floats when converting string to longdouble. This makes it dramatically easier to produce full-precision long double numbers. Fixed are the constructor (np.longdouble("1.01")), np.fromfile, np.fromstring, np.loadtxt, and np.genfromtxt (and functions based on it). Also fixed is precision loss when using np.tofile. This also fixes #1481, poor handling of bad data in fromfile and fromstring. If the function strtod_l is not available, almost none of this will work, and many tests will fail.

* MAINT: remove legacy monkeypatching of GzipFileNathaniel J. Smith2015-06-241-49/+2
| | | | | | | | | | I'm not sure exactly when GzipFile.seek started supporting the whence= argument by default -- sometime around python 2.5 from the looks of http://bugs.python.org/issue1355023. But in any case it was definitely there by 2.6, which is now the earliest version we support, so there's no longer any need to monkeypatch it in. This also fixes an error in python 3.5b2, which I haven't bothered to track down further because these are the wages of monkeypatching.
* DOC: Fix examples in npyio.py to properly import StringIO.Charles Harris2015-06-211-2/+2
| | | | | | | | | | | | In two places they were doing >>> from StringIO import StringIO Since Python 2.6 that should be >>> from io import StringIO Closes #5995.

* MAINT: Mark deprecation warning with a date and Numpy version.Charles Harris2015-06-211-0/+2
| | | | | | This is to make it easier to find and remove deprecated features. It would be a good idea if all deprecations were made with similar comments.

* BUG: loadtxt fails with complex data in Python 3.Charles Harris2015-03-111-2/+7
| | | | | | | | | | | The problem is that the Python complex type constructor only accepts a pair of numbers or a string, unlike other numeric types it does not work with byte strings. The numpy error is subtle, as loadtxt opens the file in the default text mode, but then converts the input lines to byte strings when they are split into separate values. The fix here is to convert the values back to strings in the complex converter. Closes #5655.

| | | | | | Add pickle compatibility flags to numpy.save and numpy.load. Allow only combinations that cannot corrupt binary data in Numpy arrays. Use the same default values as Python pickle.
* DOC: Reconcile docstrings and function signatures where they disagreeRobert McGibbon2015-03-021-2/+2
| | | | | Fixed typos in docstrings were updated for functions where the parameter names in the docstring didn't match the function signature.
* ENH: Add support for float hex format to loadtxt.Chris Laumann2015-02-131-1/+12
| | | | | | | | Add _floatconv to npyio.py as a default floating point converter. This uses float() as a type conversion with a fallback on (ValueError) to float.fromhex(). Closes #2517.

|\ | | | | BUG: Fix genfromtext NameValidator arguments passed to easy_dtype.
| * BUG: Fix genfromtext NameValidator arguments passed to easy_dtype.Alan Briolat2015-01-231-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | np.genfromtxt validates field names twice: once in genfromtxt and once in easy_dtype. Whilst the arguments to genfromtxt are used in the first validation, they aren't passed to easy_dtype (which is used only when dtype != None) and therefore in this case the default validation (strip non-alphanum, replace spaces) gets confusingly applied, ignoring genfromtxt's arguments. This patch adds fixes genfromtxt by passing the appropriate arguments onwards to easy_dtype. That is probably the least invasive way to fix the issue.

* | DOC: improve record/structured array nomenclature & guideAllan Haldane2015-01-221-2/+2
|/ | | | | | | | | | | This update adds a section better describing record arrays in the user guide (numpy/doc/structured_arrays.py). It also corrects nomenclature, such that "structured array" refers to ndarrays with structured dtype, "record array" refers to modified ndarrays as created by np.rec.array, and "recarray" refers to ndarrays viewed as np.recarray. See the note at the end of the structured array user guide.
