我怎么知道50个敌人进入我的双GP的次数

Question

我试过使用模数，但我对如何获得正确的数字感到困惑

public double getRewards()
 {
    gp = Math.random() * (1000 - 49 + 1) + 49;
     
     for every 50 spent on groceries a 0.05 discount per gallon of gas
     while(gp/50>49)//trying to get the number of times 50 goes into gp while gp is able to have 50 go into it
     {
         discount++;
         gp=gp/50;
     }
     
     return discount;//returns the amount discounted from your total
 }

Answer 1

您可以除以 floor（将数字四舍五入为最接近的整数）结果。例如：207 / 50 = 4.14，和Math.floor(4.14) = 4，所以Math.floor(207 / 50) = 4.

gp = Math.random() * (1000 - 49 + 1) + 49;
     
discountNumber = Math.floor(gp / 50);

discountAmount = discountNumber * 5;

console.log('50 goes into ' + gp + ' ' + discountNumber + ' times, for a savings of ' + discountAmount + ' cents');
