在 0 到 360 之间标准化方向

问题描述

我正在研究一个简单的旋转例程，它将对象旋转规范化在 0 到 360 度之间.我的 C# 代码似乎可以工作，但我对它并不完全满意.任何人都可以改进下面的代码使其更加健壮吗?

I'm working on a simple rotate routine which normalizes an objects rotation between 0 and 360 degrees. My C# code seems to be working but I'm not entirely happy with it. Can anyone improve on the code below making it a bit more robust?

public void Rotate(int degrees)
    {
        this.orientation += degrees;

        if (this.orientation < 0)
        {
            while (this.orientation < 0)
            {
                this.orientation += 360;
            }
        }
        else if (this.orientation >= 360)
        {
            while (this.orientation >= 360)
            {
                this.orientation -= 360;
            }
        }
    }

推荐答案

使用模运算:

this.orientation += degrees;

this.orientation = this.orientation % 360;

if (this.orientation < 0)
{
    this.orientation += 360;
}
