 If there is an array with no number smaller than 1.e-4 and precision is
 set to smaller than 4, values are formatted wrong and printed "0." only:

 >>> import numpy
 >>> a = numpy.array([1.e-3,1.e-4])
 >>> b = numpy.array([1.e-4,1.e-5])
 >>> print a,b
 [ 0.001   0.0001] [  1.00000000e-04   1.00000000e-05]
 >>> numpy.set_printoptions(precision=3)
 >>> print a,b
 [ 0.001  '''0.'''   ] [  1.000e-04   1.000e-05]
