[Numpy-discussion] min() of array containing NaN

Determining the minimum value of an array that contains NaN produces  
a surprising result:

 >>> x = numpy.array([0,1,2,numpy.nan,4,5,6])
 >>> x.min()
4.0

I expected 0.0.  Is this the intended behaviour or a bug?  I am using  
numpy 1.1.1.

Thanks,
Tom
