[Numpy-discussion] Strange error taking log of PyObject array

[Tom Denniston]

The following works on a float array but not an object array.  It
gives a very strange error message.

(Pdb) numpy.log(numpy.array([19155613843.7], dtype=object))
*** AttributeError: 'float' object has no attribute 'log'
(Pdb) numpy.log([19155613843.7])
array([ 23.67586166])
