Return the ceiling of the input, element-wise.
The ceil of the scalar x is the smallest integer i, such that
i >= x. It is often denoted as \(\lceil x \rceil\).
x (array_like) – Input data.
out (Tensor, None, or tuple of Tensor and None, optional) – A location into which the result is stored. If provided, it must have
a shape that the inputs broadcast to. If not provided or None,
a freshly-allocated tensor is returned. A tuple (possible only as a
keyword argument) must have length equal to the number of outputs.
where (array_like, optional) – Values of True indicate to calculate the ufunc at that position, values
of False indicate to leave the value in the output alone.
y – The ceiling of each element in x, with float dtype.
