torch.ldexp
- torch.ldexp(input, other, *, out=None) Tensor
Multiplies
input
by 2 **other
.Typically this function is used to construct floating point numbers by multiplying mantissas in
input
with integral powers of two created from the exponents inother
.- Parameters:
- Keyword Arguments:
out (Tensor, optional) – the output tensor.
Example:
>>> torch.ldexp(torch.tensor([1.]), torch.tensor([1])) tensor([2.]) >>> torch.ldexp(torch.tensor([1.0]), torch.tensor([1, 2, 3, 4])) tensor([ 2., 4., 8., 16.])
