如果x是标量,则这是标量。 See Also --- ceil, trunc, rint Notes --- Some spreadsheet programs calculate the "floor-towards-zero", in other words ``floor(-2.5) == -2``. NumPy instead uses the defi np.ceil()同理 示例 代码语言:javascript 复制 #-*-coding:utf-8-*-""" @File : tes...
round half towards zero: 向 0 进位, round(2.5) 为 2, 而 round(-2.5) 为 -2 round half away from zero: 远离 0 进位, C 语言的库函数 round 是此规则, Python 2 和 JavaScript 等多种语言也采用的是这一规则. round half to even: 向偶数进位,即之前介绍过的 Banker's rounding, 在统计学上...

In Python, you can put negative indices in a list (A[-1] means A[len(A)-1]). This makes it easy to implement dynamic programming with negative indices. When the index can take values from -L to L, prepare a dp array of length at least 2*L+1. In this array, information on po...

The processed data are provided both as NetCDF files (a common, self-describing, portable format for scien- tific data) and as.mat files (a proprietary Matlab data format that can also be opened using open-source platforms such as Python, R, and GNU Octave). Each processed file contains ...
