numeric sort in Flash6?

[thebluerider]

I wanted to sort an array by its numeric value but cant make it work. I always get a string-order instead:

-111.621366801195
-118.595917758174
-85.4975083278225
40.7332060082127

am using this code:

FOrder.sortOn([0], 16);

Can anyone tell me how to make it work or if it does work at all in Flash 6?

Hi, I am not sure but I think that the array sort method will always consider the array entries as strings. To correctly sort the array, try the following traditional sorting routine:

a = new Array();

a[0] = -111.621366801195;
a[1] = 40.7332060082127;
a[2] = -85.4975083278225;
a[3] = -118.595917758174;

for (i=0;i<a.length;i++)
{
    for (j=i+1;j<a.length;j++)
    {
        if (a[i] > a[j])
        {
            temp = a[i];
            a[i] = a[j];
            a[j] = temp;
        }
    }
}

for (z=0;z<a.length;z++)
{
    trace (a[z]);
}

stop(); 

It will produce the following output:

-118.595917758174
-111.621366801195
-85.4975083278225
40.7332060082127

PS: This routine ALWAYS will work fine, independently if the entries are numeric values or strings.

nope - check out flash manual

code:

---

var arr = [ -111.621366801195, -118.595917758174, -85.4975083278225, 40.7332060082127 ];

trace( arr);



arr.sort( function( a,b ){ return a == b ? 0 : (a>b ? 1 : -1 ); } );

trace( arr );
