Numpy - show decimal values in array results

how do I calculate that an array of python numpy or me of all the calculate decimals and not skip like.

>> A = numpy.array ([[1,2,3], [4,5,6], [7,8,9]]).

>> C = numpy.array ([[7,8,9], [1,2,3], [4,5,6]]).

&开发者_如何学JAVAgt;> A / C

array ([[0, 0, 0],
       [4, 2, 2],
       [1, 1, 1]])

but in the first vector would not have to be given to absolute zero [0.143, 0.250, 0.333]

To avoid integer division, use numpy.true_divide(A,C). You can also put from __future__ import division at the top of the file to default to this behavior.

---

Try converting one of the arrays A or C into an array of floats. For instance:

A = A * 1.0

Then the division will be floating point division.

Numpy arrays may have different types. You may also create a float array, it will always divide correctly:

>>> A = numpy.array ([[1,2,3], [4,5,6], [7,8,9]], dtype=float)
>>> A/2
array([[ 0.5,  1. ,  1.5],
       [ 2. ,  2.5,  3. ],
       [ 3.5,  4. ,  4.5]])

Notice the dtype= argument to numpy.array
