C#-四舍五入到最接近的整数 [英] C# - Rounding Down to Nearest Integer

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

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));
