nlcpy.ceil

nlcpy.ceil = <ufunc 'nlcpy_ceil'>

Returns the ceiling of the input, element-wise.

The ceiling of the scalar x is the smallest integer i, such that i >= x. It is often denoted as \lceil x \rceil.

Parameters
xarray_like

Input arrays or scalars.

outndarray or 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 array is returned. A tuple (possible only as a keyword argument) must have length equal to the number of outputs.

wherearray_like, optional

This condition is broadcast over the input. At locations where the condition is True, the out array will be set to the ufunc result. Elsewhere, the out array will retain its original value. Note that if an uninitialized out array is created via the default out=None, locations within it where the condition is False will remain uninitialized.

**kwargs

For other keyword-only arguments, see the section Optional Keyword Arguments.

Returns
yndarray

The ceiling of each element in x. If x is a scalar, this function returns the result as a 0-dimension ndarray.

参考

floor

Returns the floor of the input, element-wise.

trunc

Returns the truncated value of the input, element-wise.

rint

Computes the element-wise nearest integer.

Examples

>>> import nlcpy as vp
>>> a = vp.array([-1.7, -1.5, -0.2, 0.2, 1.5, 1.7, 2.0])
>>> vp.ceil(a)
array([-1., -1., -0.,  1.,  2.,  2.,  2.])
