mxnet.np.floor

floor(x, out=None, **kwargs)

Return the floor of the input, element-wise. The ceil of the ndarray x is the largest integer i, such that i <= x. It is often denoted as \(\lfloor x \rfloor\).

Parameters

  • x (ndarray or scalar) – Input array.

  • out (ndarray or None) – A location into which the result is stored. If provided, it must have a shape that the inputs fill into. If not provided or None, a freshly-allocated array is returned. The dtype of the output and input must be the same.

Returns

y – The floor of each element in x, with float dtype. This is a scalar if x is a scalar.

Return type

ndarray or scalar

Examples

>>> a = np.array([-1.7, -1.5, -0.2, 0.2, 1.5, 1.7, 2.0])
>>> np.floor(a)
array([-2., -2., -1.,  0.,  1.,  1.,  2.])
>>> # if you use parameter out, x and out must be ndarray.
>>> a = np.array(1)
>>> np.floor(np.array(3.5), a)
array(3.)
>>> a
array(3.)
