应该如何最好地重新编码此示例扩展方法以对所有数字类型通用？

public static float clip(this float v, float lo, float hi)
{ return Math.Max(lo, Math.Min(hi, v)); }

谢谢。

Answer 1

// IComparable constraint for numeric types like int and float that implement IComparable
public static T clip<T>(this T v, T lo, T hi) where T : IComparable<T>
{
  // Since T implements IComparable, we can use CompareTo
  if(v.CompareTo(lo)<0)
    v=lo; // make sure v is not too low
  if(v.CompareTo(hi)>0)
    v=hi; // make sure v is not too high
  return v;
}
