mindspore.numpy.exp2

mindspore.numpy.exp2(x, dtype=None)[源代码]

Calculates 2**p for all p in the input array.

Note

Numpy arguments out, where, casting, order, subok, signature, and extobj are not supported. On GPU, the supported dtypes are np.float16, and np.float32.

Parameters

x (Tensor) – input values.
dtype (mindspore.dtype, optional) – Defaults to None. Overrides the dtype of the output Tensor.

Returns

Tensor or scalar, element-wise 2 to the power x.

Supported Platforms:: Ascend GPU CPU

Examples

>>> import mindspore.numpy as np
>>> x = np.array([2, 3]).astype(np.float32)
>>> output = np.exp2(x)
>>> print(output)
