Ceiling

ceil(input: any[] | Mat | Tensor) : Number | any[] | Mat | Tensor

param input a number, or an array, matrix, tensor to get the ceiling.

returns Number | any[] | Mat | Tensor - the ceiling value of the element or elements, element-wise

This function simply finds the ceiling of numbers. For example ceil(1.5) = 2, ceil(-1.5) = -1. This can also find the ceiling of numbers element-wise, given a 1d array, 2d array, Mat object, Tensor or just a list of numbers such as this: ceil(1.5,-1.5) = 2,-1.
