jax.numpy.reciprocal

jax.numpy.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

ndarray

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])
