一、函数取整函数
函数取整，有如下四种函数
* floor():向下取整
* ceil():向上取整
* round():取最近整数
* fix():向0取整
二、例程
1、floor():向下取整
disp('floor-向下取整'); A1=floor(1.2) A2=floor(2.5) A3=floor(-2.5)
2、ceil():向上取整
disp('ceil-向上取整'); B1=ceil(1.2) B2=ceil(2.5) B3=ceil(-2.5)
3、round():取最近整数
disp('round-取最近整数'); C1=round(1.2) C2=round(2.5) C3=round(-2.5)
4、fix():向0取整
disp('round-取最近整数'); C1=round(1.2) C2=round(2.5) C3=round(-2.5)
5、整合对比
%_______________________ disp('floor-向下取整'); A1=floor(1.2) A2=floor(2.5)
A3=floor(-2.5) disp('_______________________'); %_______________________
disp('ceil-向上取整'); B1=ceil(1.2) B2=ceil(2.5) B3=ceil(-2.5)
disp('_______________________'); %_______________________ disp('round-取最近整数');
C1=round(1.2) C2=round(2.5) C3=round(-2.5) disp('_______________________');
%_______________________ disp('fix-向0取整'); D1=fix(1.2) D2=fix(2.5) D3=fix(-2.5)
disp('_______________________'); %_______________________
效果如下：
