floor(x, out=None, where=None, **kwargs)¶
Return the floor of the input, element-wise.
The floor of the scalar x is the largest integer i, such that i <= x. It is often denoted as \(\lfloor x \rfloor\).
- 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 : Tensor or scalar
- The floor of each element in x.
ceil, trunc, rint
Some spreadsheet programs calculate the “floor-towards-zero”, in other words
floor(-2.5) == -2. NumPy instead uses the definition of floor where floor(-2.5) == -3.
>>> import mars.tensor as mt
>>> a = mt.array([-1.7, -1.5, -0.2, 0.2, 1.5, 1.7, 2.0]) >>> mt.floor(a).execute() array([-2., -2., -1., 0., 1., 1., 2.])
