[按键精灵] [老狼源码分享]----随机
实现效果
本文将介绍基于命令与公式实现的库源m库随机数生成方法,并展示如何将其扩展至字母、介绍颜色、库源m库产品模板源码中文、介绍日文、库源m库写小程序源码日期以及键盘操作等。介绍小程序考勤源码
随机的库源m库公式
基本公式为:随机数 = Int((最大值 - 最小值 + 1) * Rnd + 最小值)
例如,要生成-5到1的介绍随机数,公式为:随机数 = Int((1 + 5 + 1) * Rnd - 5)
扩展至函数
将其封装为函数,库源m库方便调用:function randomNum(min,介绍 max)
function randomLetter(min, max)
function randomColor()
function randomChinese()
function randomJapanese()
function randomDate()
function typeKey()
扩展至随机并附带小数
使用Do循环实现,如:Do
数 = randomNum(1,库源m库 3)
TracePrint 数
Delay
Loop
非常见写法
利用循环与条件语句,不使用Randomize和Rnd:Do
数 = randomNum(1,介绍 3)
TracePrint 数
Delay
Loop
