问题描述
我有一个正在计算一些数字的C#应用程序.我需要四舍五入.
I have a C# app that is calculating some numbers. I need to round down.
var increment = 1.25;
var result = 50.45 - 23.70; // equals 26.75
int interval = difference / increment; // result is 21.4. However, I just want 21
我必须将 interval 设置为 int .同时，由于四舍五入行为.我总是想要最低的整数.但是，我不确定如何.
I have to get the interval to an int. At the same time, I cannot just use Convert.ToInt32 because of its rounding behavior. I always want the lowest whole number. However, I'm not sure how.
推荐答案
只需尝试一下.
int interval = Convert.ToInt32(Math.Floor(different/increment));
