Test code for user defined types in Numpy
2+
=========================================
3+
4+
This code implements fixed precision rational numbers exposed to Python as
5+
a test of user-defined type support in Numpy.
6+
7+
### Dependencies
8+
9+
* [python](http://python.org)
10+
* [numpy](http://numpy.scipy.org): Requires a patched version (see below)
11+
* [py.test](http://pytest.org): To run tests
12+
13+
On a Mac, these can be obtained through [MacPorts](http://www.macports.org) via
14+
15+
sudo port install py26-numpy py26-py
16+
17+
The original version of this code exposed several bugs in the (hopefully) old
18+
version of numpy, so if it fails try upgrading numpy. My branch which fixed
19+
all but one of the bugs uncovered is here:
20+
21+
https://github.com/girving/numpy/tree/fixuserloops
22+
23+
These changes should be incorporated in the main numpy git repo fairly soon.
24+
25+
### Usage
26+
27+
To build and run the tests, do
28+
29+
make
30+
py.test
