numpy.true_divide¶
- numpy.true_divide(x1, x2[, out]) = <ufunc 'true_divide'>¶
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: 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])
