My first C# generic function.
In computer terms, to clamp a value is to make sure that it lies between some maximum and minimum values. If it’s greater than the max value, then it’s replaced by the max, etc. I first learned it in the context of computer graphics, for colors – it’s used for instance to make sure that your raytraced pixel isn’t ‘blacker than black’. So:
public static T Clamp<T>(T Value, T Max, T Min)
where T : System.IComparable<T> {
if (Value.CompareTo(Max) > 0)
return Max;
if (Value.CompareTo(Min) < 0)
return Min;
return Value;
}
(Comments about multiple return values will be forwarded to the circular file.)
