How to use math.random function

In many programming languages, Math.random() is a function used to generate a pseudo-random floating point number between [0,1). The following are some examples of using Math.random():

1, javascript

var random = Math.random(); // 生成一个 [0,1) 之间的随机浮点数  
console.log(random);

2, Python

There is no built-in Math.random() function in Python. But you can use the random() module to achieve similar effects:

import random  
  
random_number = random.random()  # 生成一个 [0,1) 之间的随机浮点数  
print(random_number)

3, Java

In Java, you can use the java.util.Random class to generate random numbers:

import java.util.Random;  
  
Random rand = new Random();  
double random = rand.nextDouble(); // 生成一个 [0,1) 之间的随机浮点数  
System.out.println(random);

In all of these examples, Math.random() or an equivalent function is used to generate a random number within a given range. This number can be used for various purposes, such as randomly moving characters in a game, or randomly selecting options in a program.
