 Multiplication or addition of a poly1d object with a numpy float from the
 left, gives an ndarray object, instead of an poly1d. See the following
 code:

 In [38]: a=np.float64(3.0)
 In [39]: a+np.poly1d([1,1,1])
 Out[39]: array([ 4.,  4.,  4.])
 In [40]: np.poly1d([1,1,1])+a
 Out[40]: poly1d([ 1.,  1.,  4.])
