mindspore.numpy.exp2
- mindspore.numpy.exp2(x, dtype=None)[source]
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 toNone
. 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) [4. 8.]
