ceil

→Tensor

ceil(input: Tensor)

Element-wise ceiling (round toward $+\infty$ ).

Returns the least integer-valued float greater than or equal to each entry.

inputTensor

Input tensor.

Tensor

Element-wise result with the same shape as input.

Mathematical definition:

\text{out}_i = \lceil \text{input}_i \rceil

Gradient is zero almost everywhere and treated as zero in autograd.

>>> import lucid
>>> x = lucid.tensor([1.0, 2.0, 3.0])
>>> lucid.ceil(x)
