Define a function to generate random numbers From the above concept, we can create a function that takes two arguments, the highest and lowest to generate a random number between them and returns it. Below is the code to define a function to return a random number from a given range : fu...
How random is this Random Number Generator? As random as we can make it! We use javascript's internal Math.random() function which returns a Psuedo-random number in the range 0 to less than 1. We then just transform that number into an integer. The internals are complicated but rest ass...

相信大家对Math.random函数都不会陌生,调用该函数后会返回一个伪随机数,对应的取值范围是[0, 1)。在日常工作中,应用的比较多的场景是生成 UUID,比如: function uuidv4() { return 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx'.replace(/[xy]/g, function(c) { ...
var obj = Math.seedrandom(null, { pass: function(prng, seed) { return { random: prng, seed: seed }; }}); The random number sequence is the same as version 1.0 for string seeds. Version 2.0 changed the sequence for non-string seeds. ...

选择不好会产生相同的数字,在上面的测试中出现有3对相同数字,显然就用几个10的几次方作计算常量是不合格的。后在知乎上找到了答案,先看一段javascript脚本: function rnd( seed ){seed = ( seed * 9301 + 49297 ) % 233280; //为何使用这三个数?return seed / ( 233280.0 );};function rand(number){...
