I just wanted to report a marginal error triggered in the doctests:
Failed example: isnan(float('nan')) Exception raised: Traceback (most recent call last): File "C:\Python25\lib\doctest.py", line 1228, in __run compileflags, 1) in test.globs File "<doctest __main__.isnan[0]>", line 1, in <module> isnan(float('nan')) ValueError: invalid literal for float(): nan (python 2.5.4 on win XP; this might be OS specific; probably in the newer versions float() was updated, the tests on 2.6 and 2.7 are ok ): I too would be interested in a comparison with the older module with the same name: http://www.nmr.mgh.harvard.edu/Neural_Systems_Group/gary/python.html which is likely to be the same as the above mentioned one. vbr -- http://mail.python.org/mailman/listinfo/python-list
