先感谢您。
You should divide difference by realPrice and then multiply it by 100 to get percentages您应该将差异除以 realPrice,然后乘以 100 以获得百分比
decimal discountPercent = difference / realPrice * 100;
It should give you 5.(5)%
它应该给你
5.(5)%
See this working example请参阅此工作示例
decimal discountPercent = (difference / realPrice) * 100;
Console.WriteLine("Discount Percentage : {0}%",discountPercent.ToString("#.##"));
decimal discountPercent = difference / realPrice * 100;
Though this is not a programming question, but rather math question for middle school.虽然这不是编程问题,而是中学数学问题。 :D
