[Numpy-discussion] dtype behavior

[ctw]

Hi -- Can somebody here explain the following behavior:

In [1]: tst = np.array([5.])

In [2]: tst
Out[2]: array([ 5.])

In [3]: tst.shape
Out[3]: (1,)

In [4]: tst.dtype
Out[4]: dtype('float64')

In [5]: tst.dtype = np.int

In [6]: tst
Out[6]: array([         0, 1075052544])

In [7]: tst.dtype
Out[7]: dtype('int32')

In [8]: tst.shape
Out[8]: (2,)


Is this a bug? I'm running numpy version 1.1.1 and was trying to
convert the float array([5.]) to an int array([5]).
