mindspore.ops.ldexp

mindspore.ops.ldexp(x, other)[source]

Multiplies input tensor by \(2^{other}\) element-wise.

Typically this function is used to construct floating point numbers by multiplying mantissas in x with integral powers of two created from the exponents in other:

\[out_{i} = x_{i} * ( 2 ^{other_{i}} )\]

Parameters

x (Tensor) – Mantissas tensor.
other (Tensor) – Exponents tensor, typically integers.

Returns

Tensor

Supported Platforms:: Ascend GPU CPU

Examples

>>> import mindspore
>>> x = mindspore.tensor([1.], mindspore.float32)
>>> other = mindspore.tensor([1, 2, 3, 4], mindspore.int32)
>>> out = mindspore.ops.ldexp(x, other)
>>> print(out)
[ 2.  4.  8. 16.]
>>> x = mindspore.tensor([[1.], [2]], mindspore.float32)
>>> other = mindspore.tensor([[1.], [2]], mindspore.int32)
>>> out = mindspore.ops.ldexp(x, other)
>>> print(out)
[[2.]
