+# reciprocal
+
+## NumPy
+
+```
+numpy.reciprocal(x, /, out=None, *, where=True, casting='same_kind', order='K', dtype=None, subok=True[, signature, extobj]) → ndarray
+```
+
+## CuPy
+
+```
+cupy.reciprocal(x, /, out=None, *, casting='same_kind', dtype=None) → ndarray
+```
+
+## dask.array
+
+```
+dask.array.reciprocal(x, /, out=None, *, where=True, casting='same_kind', order='K', dtype=None, subok=True[, signature, extobj]) → array
+```
+
+## JAX
+
+```
+jax.numpy.reciprocal(x, /) → ndarray
+```
+
+## MXNet
+
+```
+np.reciprocal(x, out=None, **kwargs) → ndarray
+```
+
+## PyTorch
+
+```
+torch.reciprocal(input, *, out=None) → Tensor
+```
+
+Supports integral inputs, which are subsequently promoted to default scalar dtype.
+
+## TensorFlow
+
+```
+tf.math.reciprocal(x, name=None) → Tensor
+```
+
+Supports all numeric dtypes.
