[Numpy-discussion] Easter Egg or what I am missing here?

Please would anyone tell me the following is an undocumented bug otherwise I will lose faith in everything: == import numpy as np years = [2004,2005,2006,2007] dates = [20040501,20050601,20060801,20071001] for x in years: print 'year ',x xy = np.array([x*1.0e-4 for x in dates]).astype(np.int) print 'year ',x == Or is this a recipe to blow up a power plant?
