Are you sure?
In [4]: type(np.ceil(-0.0))
Out[4]: <type 'numpy.float64'>

Hi All,
I use numpy 1.4.1 on Debian squeeze amd64.
I noticed that ceil() is not working properly.
If the input to ceil() is a float I expect a float to be returned but for inputs
in (-1.0, 0.0) the result is of type integer.
In [65]: np.__version__
Out[65]: '1.4.1'
In [66]: np.ceil(-1.1)
Out[66]: -1.0
In [67]: np.ceil(-0.734)
Out[67]: -0
In [68]: np.ceil(-0.256)
Out[68]: -0
In [69]: np.ceil(-0.0)
Out[69]: -0
In [70]: np.ceil(0.2)
Out[70]: 1.0
Best wishes
Christian
