I've search a long time but I can't find the solution. I'm searching for a kind of object coll. where, when I send a number of index which doesn't exist the object send the value of the nearest index.

if I send 8 it will find the index 7 and return 66.

I precise my index are really large value because they report the position in a file. and I need to connect a phazor with a snapshot to this object. it is possible to find a solution ?

I do this kind of thing with JavaScript objects now.

But how did u do that in Javascript dhjdhjdhj ? have u an exemple ?

Well, I've only been hacking JavaScript for a week or so, but here's an example that works in node.js and would probably work in Max

obj[9999999] = -1; // Fencepost --- make it easy

function w(s)
{
    //post(s); post();
	console.log(s);
}

var obj = {};
obj[1] = 64;
obj[3] = 65;
obj[7] = 66;
obj[9] = 97;
obj[20] = 88;   

obj[9999999] = -1; // Fencepost --- make it easy 

// get the indexes and sort them
var indexes = [];
for (var i in obj)
{
    indexes.push(i);
}

indexes.sort(
               function(a,b)
               {
                  return a-b;
               }
            );

    function NearestIndex(arr, index)
    {
        var left = 0;
        var right = arr.length - 1;
        var mid = 0;
        while (left
        {
            mid = parseInt( (left + right) / 2);
            if (index > arr[mid])
            //then
                left = mid + 1;
            else if (index < arr[mid])
            //then
                right =  mid - 1;
            else break;

        if (index != arr[mid])
           //then
              mid--;
        return mid;
    }

you can also do pretty slick interpolation of values with pattr storage (see ex. in the help file)
