mars.tensor.ceil

mars.tensor.ceil(x, out=None, where=None, **kwargs)[source]

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 \(\lceil x \rceil\).

Parameters
  • 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.

  • **kwargs

Returns

y – The ceiling of each element in x, with float dtype.

Return type

Tensor or scalar

Examples

>>> import mars.tensor as mt
>>> a = mt.array([-1.7, -1.5, -0.2, 0.2, 1.5, 1.7, 2.0])
>>> mt.ceil(a).execute()
array([-1., -1., -0.,  1.,  2.,  2.,  2.])
