基本上像骰子一样返回1-6，

return Math.round(Math.random() * 5 + 1);

重要的

The following code works only if the minimum value is `1`. It does not work for minimum values other than `1`.

如果你想得到一个介于1（且只有1）和6之间的随机整数，你可以计算：

const rndInt=数学地板（Math.random（）*6）+1控制台日志（rndInt）

哪里：

1是起始编号6是可能结果的数量（1+start（6）-end（1））

var x = 6; // can be any number
var rand = Math.floor(Math.random()*x) + 1;

我在搜索用TypeScript编写的随机数生成器，在阅读了所有答案后，我写了这个，希望它对TypeScript程序员有用。

    Rand(min: number, max: number): number {
        return (Math.random() * (max - min + 1) | 0) + min;
    }   

范围[a，b]内的加密强随机整数（假设：a<b）

let rand=（a，b）=>a+（b-a+1）*crypto.getRandomValues（新Uint32Array（1））[0]/2**32|0console.log（兰特（1,6））；

如果您想覆盖负数和正数，并确保其安全，请使用以下方法：

JS解决方案：

function generateRangom(low, up) {
  const u = Math.max(low, up);
  const l = Math.min(low, up);
  const diff = u - l;
  const r = Math.floor(Math.random() * (diff + 1)); //'+1' because Math.random() returns 0..0.99, it does not include 'diff' value, so we do +1, so 'diff + 1' won't be included, but just 'diff' value will be.
  
  return l + r; //add the random number that was selected within distance between low and up to the lower limit.  
}

Java解决方案：

public static int generateRandom(int low, int up) {
        int l = Math.min(low, up);
        int u = Math.max(low, up);
        int diff = u - l;

        int r = (int) Math.floor(Math.random() * (diff + 1)); // '+1' because Math.random() returns 0..0.99, it does not include 'diff' value, so we do +1, so 'diff + 1' won't be included, but just 'diff' value will be.
  
        return l + r;//add the random number that was selected within distance between low and up to the lower limit.      
}
