Documentation

treetensor.torch.floor(input, *args, **kwargs)

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

Examples:

>>> import torch
>>> import treetensor.torch as ttorch
>>> ttorch.floor(ttorch.tensor([[1.2, -1.8], [-2.3, 2.8]]))
tensor([[ 1., -2.],
        [-3.,  2.]])

>>> ttorch.floor(ttorch.tensor({
...     'a': [[1.2, -1.8], [-2.3, 2.8]],
...     'b': {'x': [[1.0, -3.9, 1.3], [-4.8, -2.0, 2.8]]},
... }))

└── b --> <Tensor 0x7fbf53334f10>
    └── x --> tensor([[ 1., -4.,  1.],

Description From Torch v1.9.0+cu102

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.

\[\text{out}_{i} = \left\lfloor \text{input}_{i} \right\rfloor\]

Args:

input (Tensor): the input tensor.

Keyword args:

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.])
