Assign a range to an integer variable

[Sanjeev Mehta]

Is there some way I can assign a fixed range to a variable.
For example, can I fix the range of variable i to 0 to 255 such that

int i = 0;
int a = 50;
int b = 100;
int c = 110;
i = a + b + c;

I want this to return me i as 255 and not 260. Is there some way I can achieve this rounding?
Thanks

Why not just write a quick and dirty method that will clamp the int to the range -- at the time that you call it?

Yes I could do that. Was just wondering if there was another way to go about it.
Thanks

Primitive types have no notion of "ranges". (Neither to the default objects that represent the primitives.) Unlike Ada we can't simply define native-looking types, allow operator overloading to act on them, and so on.

Except for the absolute minimum and maximum values (e.g. Integer.MIN_VALUE and Integer.MAX_VALUE).

Sanjeev, check out Math.max and Math.min.

Well, yeah, but we're talking about substantially smaller numbers here.

Sure, you can design your own type.

You introduce a class called RangeInt256 or something and give it properties you want.
