clamp

Suppose I have a value , I usually do this to "clamp" it to a range, here the range [0..1] . That is if it is below the range start, increase it to the range start, it above the range end, reduce it to the range end. clampedValue = Math.max(0, Math.min(1, value)); Is there any built in function for clamping to a range? Is there any built in function for clamping to a range? No. weston Having looked at the generic clamp method offered up in another answer, it is worth noting that this has boxing/unboxing considerations for primitive types. public static <T extends Comparable<T>> T clamp(T val,

I would like to clamp a value x to a range [a, b] : x = (x < a) ? a : ((x > b) ? b : x); This is quite basic. But I do not see a function "clamp" in the class library - at least not in System.Math . (For the unaware 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.) Lee You could write an extension method: public static T Clamp<T>(this T val, T min, T max) where T : IComparable<T> { if (val.CompareTo(min) < 0) return min; else if(val.CompareTo(max) > 0) return max; else return val; }

I have the following code: new_index = index + offset if new_index < 0: new_index = 0 if new_index >= len(mylist): new_index = len(mylist) - 1 return mylist[new_index] Basically, I calculate a new index and use that to find some element from a list. In order to make sure the index is inside the bounds of the list, I needed to write those 2 if statements spread into 4 lines. That's quite verbose, a bit ugly... Dare I say, it's quite un-pythonic . Is there any other simpler and more compact solution? (and more pythonic ) Yes, i know I can use if else in one line, but it is not readable: new

Is there a more efficient way to clamp real numbers than using if statements or ternary operators? I want to do this both for doubles and for a 32-bit fixpoint implementation (16.16). I'm not asking for code that can handle both cases; they will be handled in separate functions. Obviously, I can do something like: double clampedA; double a = calculate(); clampedA = a > MY_MAX ? MY_MAX : a; clampedA = a < MY_MIN ? MY_MIN : a; or double a = calculate(); double clampedA = a; if(clampedA > MY_MAX) clampedA = MY_MAX; else if(clampedA < MY_MIN) clampedA = MY_MIN; The fixpoint version would use
