reciprocal
(x)[source]¶ Return the reciprocal of the argument, element-wise.
LAX-backend implementation of
reciprocal()
. Original docstring below.reciprocal(x, /, out=None, *, where=True, casting=’same_kind’, order=’K’, dtype=None, subok=True[, signature, extobj])
Calculates
1/x
.- Parameters
x (array_like) – Input array.
- Returns
y – Return array. This is a scalar if x is a scalar.
- Return type
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])
