numpy.true_divide()

numpy.true_divide(x1, x2[, out]) =

Returns a true division of the inputs, element-wise.

Instead of the Python traditional ?floor division?, this returns a true division. True division adjusts the output type to present the best answer, regardless of input types.

Parameters:

Parameters:	x1 : array_like Dividend array. x2 : array_like Divisor array.
Returns:	out : ndarray Result is scalar if both inputs are scalar, ndarray otherwise.

x1 : array_like

Dividend array.

x2 : array_like

Divisor array.

Returns:

out : ndarray

Result is scalar if both inputs are scalar, ndarray otherwise.

Notes

The floor division operator // was added in Python 2.2 making // and / equivalent operators. The default floor division operation of / can be replaced by true division with from __future__ import division.

In Python 3.0, // is the floor division operator and / the true division operator. The true_divide(x1, x2) function is equivalent to true division in Python.

Examples

>>> x = np.arange(5)
>>> np.true_divide(x, 4)
array([ 0.  ,  0.25,  0.5 ,  0.75,  1.  ])

>>> x/4
array([0, 0, 0, 0, 1])
>>> x//4
array([0, 0, 0, 0, 1])

>>> from __future__ import division
>>> x/4
array([ 0.  ,  0.25,  0.5 ,  0.75,  1.  ])
>>> x//4
array([0, 0, 0, 0, 1])
