nki.language.ceil#

nki.language.ceil(x, dtype=None)[source]#

Ceiling of the input, element-wise.

((Similar to numpy.ceil))

Warning

This API is experimental and may change in future releases.

The ceil of the scalar x is the smallest integer i, such that i >= x.

Parameters:

  • x – a tile.

  • dtype – (optional) data type to cast the output type to (see Supported Data Types for more information); if not specified, it will default to be the same as the data type of the input tile.

Returns:

a tile that has ceiling values of x.

Examples:

import nki.language as nl

# nki.language.ceil -- rounds 3.2 up to 4.0
a = nl.full((128, 512), 3.2, dtype=nl.float32, buffer=nl.sbuf)
c = nl.ceil(a)
expected = nl.full((128, 512), 4.0, dtype=nl.float32, buffer=nl.sbuf)
assert nl.equal(c, expected)

# nki.language.ceil -- rounds -3.7 up to -3.0
a = nl.full((128, 512), -3.7, dtype=nl.float32, buffer=nl.sbuf)
c = nl.ceil(a)
expected = nl.full((128, 512), -3.0, dtype=nl.float32, buffer=nl.sbuf)
assert nl.equal(c, expected)
