ldexp

→Tensor

ldexp(input: Tensor, exponent: Tensor | Scalar)

Element-wise $\text{input} \cdot 2^{\text{exponent}}$ .

Differentiable through both arguments (uses exp * log(2) internally rather than integer bit twiddling), so safe to chain inside autograd graphs.

inputTensor

Mantissa.

exponentTensor or Scalar

Power-of-two exponent; broadcastable to the shape of input.

Tensor

Broadcast shape of input and exponent.
