numpy.reciprocal()

numpy.reciprocal(x[, out]) =

Return the reciprocal of the argument, element-wise.

Calculates 1/x.

Parameters:

Parameters:	x : array_like Input array.
Returns:	y : ndarray Return array.

x : array_like

Input array.

Returns:

y : ndarray

Return array.

Notes

Note

This function is not designed to work with integers.

For integer arguments with absolute value larger than 1 the result is always zero because of the way Python handles integer division. For integer zero the result is an overflow.

Examples

>>> np.reciprocal(2.)
0.5
>>> np.reciprocal([1, 2., 3.33])
array([ 1.       ,  0.5      ,  0.3003003])
