Java版 微信红包算法详解编程语言

 private double[] divide(double totalMoney,int num,double minMoney){ 

 double[] each = new double[num]; 

 for(int i=0;i num-1;i++){ 

 //计算最大安全值，保证不会超出 。如果安全值越大，价格波动越大 .建议是平均值 

 double maxSafeMoney = (totalMoney - (num-1-i)*minMoney) / (num-1-i); 

 //随机算出最小值，保证不低于最小值 

 each[i] = Math.random()*(maxSafeMoney-minMoney)+minMoney; 

 //计算当前剩下的钱 

 totalMoney = totalMoney - each[i]; 

 each[num-1] = totalMoney; 

 return each; 

 @Test 

 public void test3(){ 

 double[] rs = divide(200,10,0.01); 

 for(double each:rs){ 

 System.out.format("%.2f/n",each); 

 }

结果：
