3. 使用场景与小贴士 · Use Cases & Tips
-
抽奖与点名 · Raffles & Roll Calls:
将参与者编号,使用单个随机整数模式即可快速选出获奖人或被点名的同学。
Assign numbers to participants and use the single-integer mode to draw winners or select people at random. -
随机分组与排序 · Random Grouping & Ordering:
使用“多个随机整数列表 + 不允许重复”,可生成随机顺序或用于将成员平均分组。
Use “multiple integers + no duplicates” to create random orderings for fair grouping or seat assignments. -
教学与模拟实验 · Teaching & Simulation:
在数学、统计或编程教学中,用随机数构造样本数据、实验场景或蒙特卡洛模拟。
In math, statistics, or programming classes, random integers serve well for sample data or Monte Carlo-style experiments. -
注意事项 · Notes:
本工具依赖浏览器的伪随机数生成算法,适用于日常学习、教学、简单抽样,
但不适合对安全性有严格要求的场景(如密码学密钥生成等)。
This tool uses the browser’s pseudo-random generator, good for daily use and teaching but not for security-critical purposes like cryptographic key generation.
