torch.floor — PyTorch 2.5 documentation (original) (raw)

torch.floor(input, *, out=None) → Tensor¶

Returns a new tensor with the floor of the elements of input, the largest integer less than or equal to each element.

For integer inputs, follows the array-api convention of returning a copy of the input tensor.

outi=⌊inputi⌋\text{out}_{i} = \left\lfloor \text{input}_{i} \right\rfloor

Parameters

input (Tensor) – the input tensor.

Keyword Arguments

out (Tensor, optional) – the output tensor.

Example:

a = torch.randn(4) a tensor([-0.8166, 1.5308, -0.2530, -0.2091]) torch.floor(a) tensor([-1., 1., -1., -1.])
