基于VFP的随机数研究与应用

Research and Application of Random Number Based on VFP

随机数研究与应用可以模拟、解决各领域活动中的一些实际问题.根据随机数的产生特点可知,随机数的产生是通过随机函数参数的选取来控制的.通过对随机数的检验标准和分类的概述,了解真随机数和伪随机数的区分.针对VFP中随机函数RAND()的功能特点及RAND()使用过程中出现的随机函数重复数列和重复值等问题,结合实际工作和生活中所出现的问题探讨对应的解决办法.

The research and application of random numbers can simulate and solve some practical problems in various fields of activities.According to the characteristics of random numbers,the generation of random numbers is controlled by the selection of random function parameters.Through an overview of the inspection standards and classification of random numbers,we can understand the distinction between true random numbers and pseudo-random numbers and pseudo-random number generators.For the random function rand()in VFP,this paper discusses the corresponding solutions to the problems in practical work and life.
