* | BUG: Fix zero divide warning in financial.pmt.Fei Liu2015-02-172-2/+10
| | | | | | | | | | | | | | | | | | The pmt function in financial.py does a zero divide when rate=0 because error because the alternatives in np.where() are evaluated befor the selection is made.first before going into the function however, the denominator can be zero at that time. Closes #4701.

* | | TST: Make loadtxt able to load floats as hex strings.Charles Harris2015-02-131-0/+13
| | | | | | | | | | | | The strings must be produced by the python float.hex method.
* | | 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.
| * | MAINT: Make argument determination in NameValidator more precise.Charles Harris2015-01-232-4/+9
| | | | | | | | | | | | | | | | | | | | | The function was useing `'u' in case_sensitive` to detect `upper`. Make that more precise with `case_sensitive.startswith('u'). Raise ValueError if case_sensitive has unrecognized value.
| * | TST: Fix bug in test_dtype_with_converters_and_usecols.Charles Harris2015-01-231-2/+2
| | | | | | | | | | | | | | | | | | | | | The case_sensitive argument to np.recfromcsv has a default value of 'lower'. That value was not previously correctly passed on, but is now, so the previous expected values in this test were incorrectly upper cased.
| * | BUG: Fix genfromtext NameValidator arguments passed to easy_dtype.Alan Briolat2015-01-232-1/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | This allows one to specify the maximum number of row processed in in a call. The new functionality allows for reading more complex data formats. For instance, multiple calls can be used to read in multiple arrays stored in a single file. Closes #5084. Closes #5093.

| | | | | | | | | | | | | | | | | | | | | | | | Current loadtxt with `comments=None` considers the string `'None'` as a comment symbol. Fixed by making split_line method check if comments is None. Closes #5155.
* | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is an ugly hack to preserve backwards compatibility for code that uses matrices. It is needed since both diag and diagonal have been changed to preserve subtypes otherwise. Note that a.diagonal() still returns matrices when a is a matrix.

| | |/ / | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This PR adds an implementation of `nanprod`. The actual function is a two-liner adapted from `nansum`. Most of this PR consists of documentation and tests (for which I took the opportunity to do some consolidation). A method with the same functionality exists in pandas, and I was surprised to discover that it's not in numpy.
